The Federal Bureau of Investigation arrested two members of the New Haven Police Department and three others when they executed a search and seizure warrant today at NHPD headquarters and several other buildings around the city,

representatives of the New Haven division of the FBI said.

Marybeth Miklos of the New Haven FBI confirmed that federal agents arrested Lt. William White, supervisor of the narcotics squad, and Detective Justen Kasperzyk after the raids began early this afternoon. The names of the others arrested have not been released.

The raids were part of an ongoing investigation that has been active since at least 2006, Miklos said. She could not release any further details about the investigation or the arrests because the indictments are still sealed, she said.

FBI agents are still out and working on the investigation, she said, so she could not comment on whether the FBI intends to make further arrests.

The apprehended individuals were set to appear before federal magistrates in Hartford at 3:30 today, Miklos said, after which the U.S.

Attorney’s office was expected release more information about the charges.

New Haven Mayor John DeStefano plans to hold a press conference later today.

The NHPD has not yet responded to requests for comment.
