R. Lindley DeVecchio was expected to be released on $1 million bail after his arraignment, The New York Times reported, combining $100,000 in cash with guarantees from five retired agents. About 45 of DeVecchio's former colleagues packed a courtroom in Brooklyn to support him.
Brooklyn District Attorney Charles Hynes said DeVecchio developed a close relationship with Gregory Scarpa Sr., a captain in the Colombo crime family. Scarpa died in 1994 in prison.
"This is the most stunning example of official corruption I have ever seen," Hynes said.
Hynes said his investigation began with information from a Massachusetts congressman who has been investigating FBI involvement with organized crime.
DeVecchio's supporters say he has already been exonerated by a Justice Department investigation.
