According to figures released by the gardaí in response to a freedom of information request, the total overtime spend rose 47.6% going from €20m to €29.58m between January of June of this year.
The main driver behind the increase is the extra resources deployed in Dublin to combat the ongoing Kinahan-Hutch feud.
Last week, innocent Dublin City Council worker, Trevor O’Neill, aged 42, became the 10th victim, in a case of mistaken identity, when he was shot dead while on holidays in Majorca. Nine of the 10 deceased are all believed to be victims of the Kinahan gang.
The figures show Dublin has accounted for 73% of the €9.5m increase in overtime payments for the first six months of this year.
The additional spend was driven by the number of overtime hours worked increasing from 618,354 to 904,689 for the first six months of the year.
Much of the focus of the ongoing Garda operations has been in the north inner city area and the overtime figures reflect that.
The figures show that the overtime bill in the North Central Division for the first six months of 2016 totalled €4.55m. That represent a jump of 100% on the €2.27m paid out in the first six months of 2015.
The overall overtime bill for the Dublin Metropolitan Area has risen from €11.47m for the first six months of last year to €18.47m for the same period this year.
The large rise in overtime hours worked has resulted in an overtime bonanza for individual gardaí. The figures show one sergeant in the Dublin Metropolitan area received €34,666 in overtime payments between January and June.
Two others received payments of over €30,000 with one garda receiving €31,690 in overtime payments and the second receiving €30,704.
Another five members including a sergeant and an inspector received overtime payments between €25,000 and €30,000 while another 12 members, including eight sergeants, received overtime payments between €20,000 and €25,000.
The Garda FoI unit decided not to identify the district in which the individual gardaí work as it was deemed personal information.
An accompanying statement from the Garda FoI unit points out that in February 2016, €5m was allocated by the Department of Justice to resource additional measures to tackle organised crime.
It states that €3.7m was devolved to Garda regions/branches in the form of overtime in order to facilitate multiple rolling checkpoints, extra patrols and implementing measures to tackle organised crime. It states that the remainder was used to provide operational equipment to support the measures and the €5m was fully spent by the end of June.
The FoI unit also says an additional €5m to fund Operation Thor from November to March 2016 has been fully spent.
