The largest-ever UK modern slavery ring, which forced more than 400 people to work for a pittance while their criminal masters earned £2 million, has been smashed.
A three-year police investigation uncovered a well-organised criminal gang led by the Brzezinski family - which preyed on the homeless, ex-prisoners and alcoholics, from Poland.
The ring lured and then trafficked vulnerable victims to the UK with the promise of good money, but instead housed them in squalor, and used them as what a judge described as "commodities".
Victims were paid as little as 50p for a day's labour and in one case a worker was given coffee and a chicken as payment for redecorating a house.
Another man had to wash in a canal because he had no other access to water, while one house's leaky toilet had to be plugged with an old duvet, such was the standard of disrepair.
One victim, describing "horrible" living conditions, said: "I would say some homeless people here in the UK live better than I lived after I arrived over here."
Victims were reduced to recycling used cigarette butts off the street, and going to soup kitchens and food banks to get enough to eat.
Meanwhile, the gang's bosses lived the high life off the backs of those they exploited, sporting lavish clothes, and driving luxury cars, including a Bentley.
After the end of two trials, it can now be reported how five men and three women, all originally from Poland, exploited their destitute victims for pure "greed".
They have all now been convicted of modern slavery offences and seven of their number, of money laundering.
Jurors heard the accounts of more than 90 victims, but it is believed at least 350 more had been through the gang's hands, who had since either returned to their homeland, could not be traced, or were too scared to come forward.
At the end of the second case last month, a jury at Birmingham Crown Court convicted two men, 52-year-old Ignacy Brzezinski, of Beechwood Road, West Bromwich, and Wojciech Nowakowski, 41, of James Turner Street, Birmingham, of modern slavery offences.
A third, Jan Sadowski, 26, of Dartmouth Street, West Bromwich, admitted his part on the first day of trial.
Sentencing Ignacy to 11 years on Friday, Judge Mary Stacey described the "high functioning alcoholic" as having "direct control", and "living in the nerve centre of the organisation".
She said: "As the head of the family, he set the tone of the operation, and also enjoyed the fruits of the conspiracy, riding round in his Bentley and a fleet of high performance cars at his disposal.
The court heard that having been given bail after breaking his leg falling down the stairs during the trial, he had gone on the run since conviction, having "abused the compassion of the court", the judge added.
Jailing Nowakowski for six-and-a-half years, Judge Stacey described him as a one-time victim of the conspiracy who had risen to become a "spy and enforcer" for the gang.
She said: "He was fully embedded and his role was to keep the conspirators in line.
"Described as a top dog and perhaps a sergeant major, he enjoyed the power over the others."
She accepted Nowakowski had suffered a "hard life", and "battled alcoholism as well, to the point of losing his toes to frostbite after falling asleep in the snow in Poland, after drinking too much".
Judge Stacey, jailing father-of-two Sadowski - the only defendant to plead guilty - for three years for his "lesser role".
However, she said he had been integral to setting up trafficked victims' bank accounts, for the benefit of the gang's bosses.
At a previous trial ending in February, leading conspirator Marek Chowanic, along with Ignacy's cousin, Marek Brzezinski, recruitment consultant Julianna Chodakiewicz, Natalia Zmuda and Justyna Parczewska, the group's matriarch, were all convicted of their roles.
At their sentencing, Judge Stacey said their "degradation" of fellow human beings had been "totally unacceptable", jailing the five for between 11 and four-and-a-half years.
She said the defendants had subjected victims to a "demi-life of misery and poverty", robbing them of their dignity and humanity "without care or regard for the rights of the individuals affected".
She added: "Any lingering complacency after the 2007 bi-centenary celebrations of the abolition of the English Slave Trade Act was misplaced.
Together the group helped in the targeting and trafficking of people from their Polish homeland, placing them in cramped, rat-infested accommodation in the Black Country and putting them to work on farms, rubbish recycling centres and poultry factories.
In some cases, the gang waited outside the front gates of jails in Poland, to approach ex-cons who had just been released.
Victims, aged 17 to over 60, were housed across at least nine different addresses in West Bromwich, Walsall, Sandwell and Smethwick, crammed up to four to a room, fed out-of-date food, and forced to scavenge for mattresses to sleep on.
Some had no working toilets, heating or furniture.
If any complained, gang enforcers would humiliate, threaten or beat them up, while "house spies" - previously trafficked individuals turned trusted informers - kept an eye on the workers.
On several occasions, anti-slavery investigators with charity Hope for Justice, and West Midlands Police, uncovered shocking brutality against those who stepped out of line.
One man who complained about living conditions and pay had his arm broken, was refused medical care, and then ejected from the accommodation because his injury left him unable to work.
Another was stripped naked in front of other workers, doused in surgical chemical iodine, and told that the gang would remove his kidneys if he did not keep quiet.
The gang seized identity cards, registered victims for National Insurance and opened bank accounts in the victims' names using bogus addresses, while their criminal masters also claimed benefits without their knowledge.
The ring also infiltrated a recruitment agency, meaning work could be directly sourced, without raising suspicions with third parties.
Victims would in some cases be "frog-marched" to cash points, to withdraw money and told they owed debts for transport costs, rent and food, the charity said.
When one worker died of natural causes at an address controlled by the gang, Parczewska ordered that his ID and personal effects be removed from his pockets before paramedics arrived.
Judge Stacey said the conspiracy, which ran from June 2012 until October 2017, was the "most ambitious, extensive and prolific" modern day slavery network ever uncovered.
Investigators believe it is the largest such criminal prosecution of its type in Europe, to date.
The gang operation was smashed after victims were uncovered by anti-slavery charity Hope for Justice.
The charity said 51 of the victims eventually made contact through its painstaking outreach efforts at two drop-in centres.
The organisation was then able to flag the slavery ring's existence to police.
West Midlands Police then launched an investigation in February 2015.
It has led to what is believed to be the biggest such modern slavery prosecution of its kind in Europe.
The judge praised police but also the charity's "absolutely remarkable" work, adding:
"One wonders how long this would have gone undetected and flourished, otherwise."
Opening the second of two trials, Caroline Haughey QC, prosecuting, said:
Chowanic, 30, of Mount Street, Walsall, Marek Brzezinski, 50, of Lindley Avenue, Tipton, Chodakiewicz, 24, of Evesham, Worcestershire, Zmuda, 29, of Canute Close, Walsall, and Parczewska, 48, of Beechwood Road, West Bromwich, were jailed in March.
Chowanic was jailed for 11 years, Marek Brzezinski, nine years, Chodakiewicz, five-and-a-half years, Parczewska, five years and Zmuda, four-and-a-half years.
