Detectives investigating a spate of pickpocketing offences at Sheffield railway station have released the photographs of three men they want to trace.
Two of the men - 57-year-old Andrzej Zimnocha and 49-year-old Zbigniew Dariusz Dudek - are known to the police but the third is not.
All three are wanted over pickpocketing offences at Sheffield and Birmingham New Street railway stations between April and November 2009.
The police appeal for information follows the successful prosecution of pickpocket Mikolaj Andrzej Szyjkowski, 50, of Scotia Road, Stoke, who was sentenced at Sheffield Crown Court in December 2010 after pleading guilty to conspiracy to steal.
Detective Sergeant Bill Henry, the senior investigating officer in the case, said the trio are believed to be originally from Poland.
“It is not common practice for us to release the names of people we would like to speak to in connection with crimes committed on the railway,” he said.
“But we have taken this unprecedented step because these men have been identified as people we need to make contact with as a matter of urgency.
“The men may be living in the Sheffield or Birmingham New Street areas, or may now have moved elsewhere in the country or even gone back to Poland.
“We are investigating a number of thefts and we welcome any information as to these men’s whereabouts, especially as the thefts have caused unnecessary stress and inconvenience to the vulnerable and elderly victims of these crimes.”
Anyone with information should call British Transport Police on 0800 405040 quoting background reference B6/NEA of 25/01/2011.
