Paul Scriven, Leader of Sheffield council accused Cllr Curran of taking public survey data from the Lib Dems, which had been collected during the general election campaign. He reported Cllr Curran to the police, and wrote to Labour group leader Cllr Julie Dore requesting he be suspended pending the investigation.
South Yorkshire Police today confirmed that the investigation had been dropped.
Acting Detective Chief Inspector Bob Chapman said: “South Yorkshire Police has investigated a complaint made by the Liberal Democrats relating to Ben Curran.
“Following this investigation, no further action is to be taken. This outcome has been agreed with all those involved.”
A spokesperson for Sheffield Liberal Democrats said: “South Yorkshire Police have confirmed to us that Councillor Curran did obtain the files of personal data two days before he defected to the Labour Party, but that he did not pass it on and that it has now been returned.
“As he obtained the data while he was still a Liberal Democrat councillor, they have said he did not commit an offence and we will not take this matter any further.”
The Labour group did not suspend Cllr Curran, who remained silent on the matter until releasing a statement yesterday, in which he said: “The Police have confirmed that there is no case to answer. I hope that, as Councillors, we can all now focus on representing our constituents and doing what is best for Sheffield.”
