An unmarked FBI van sits outside Bridgewater Town Hall as agents scour through evidence inside.
FBI agents worked well into the evening hours on Wednesday after they raided Bridgewater Town Hall.
First Selectman Bill Stewart said he was unaware of nature of the raid.
"No idea why the FBI is investigating," Stewart said. "The FBI hasn't told me anything."
According to Nancy Hawley, Chairman of the Bridgewater Board of Finance, between 12 and 15 FBI agents came into Town Hall around 12:15 p.m. Hawley said she received calls from several town hall employees about the raid. The employees were asked to back away from their desks, Hawley said.
Federal agents collected files and other documents from the town hall offices, according to employees.
Sources said the documents go back at least to 2007.
Connecticut Attorney General George Jepsen has been conducting an investigation into a charitable fund administered by the Board of Selectman and the Board of Finance in Bridgewater.
The Burnham Fund was established in 1925 to help provide relief to the poor in Bridgewater, according to Jepsen. He is currently investigating whether the money from the fund has been misused.
It was unclear if the FBI raid was connected in any way to the Burnham Fund.
