Officials in Britain investigating the horse meat mis-labelling scandal will continue examining evidence today after three more plants were raided.
The Food Standards Agency (FSA) visited two premises in Tottenham, London and one in Hull, Yorkshire, on Thursday.
Investigators, accompanied by police officers and local authority officials, made seizures at the three sites and removed meat samples for testing.
An FSA statement said: “Computers and documentary evidence have been removed from these premises, as well as meat samples that have been taken for testing.”
The FSA also said it had passed on evidence to Europol – the European Union’s law enforcement agency and the authorities in dozens of countries.
It said: “The FSA has submitted a full file and evidence on this issue to Europol.
“The agency has continued to provide information to Europol, and this information has now been analysed by both Europol and law enforcement agencies in 35 countries – across Europe and elsewhere.”
One of the plants raided in north London, Dinos & Sons Continental Foods, said it was “co-operating with local trading standards officers and the FSA”.
Meanwhile three men who were arrested on Thursday on suspicion of offences under the Fraud Act have been released on bail, Dyfed Powys Police said.
Dafydd Raw-Rees, 64, the owner of Farmbox Meats near Aberystwyth, and a 42-year-old man were arrested in Wales.
A 63-year-old man was also arrested on suspicion of the same offence at Peter Boddy Slaughterhouse in Todmorden, West Yorkshire.
The men will return to answer bail in Aberystwyth at a later date, police said.
