The source, who asked not to be identified, said Camden officers Jason Stetser, Antonio Figueroa and Kevin Parry, were first investigated about a year ago for a possible theft.

Sometime last week, federal investigators took the officers in for questioning, the source said.

"They were stealing," the source said, declining to elaborate further.

The source could not confirm the accuracy of a recent report on NBC-10 that claimed via its own sources that the officers had made arrests in dozens of drug cases that may now be jeopardized because of the investigation.

Neither the FBI or the Camden County Prosecutor's Office would comment on any potential investigation of Camden police officers.

Camden Police Inspector Mike Lynch confirmed that the officers had been suspended but declined to comment further.

In February, Figueroa and a handful of other Camden officers were named as defendants in a federal civil rights lawsuit filed by a city resident claiming he was harassed and profiled by police.

In April, a state prison inmate from Camden filed a federal lawsuit against Parry and Stetser, claiming Parry beat him while Stetser watched during an apparent drug raid at a Camden home in July 2008.

The inmate claims in the complaint that he was interviewed by Camden's Internal Affairs but that "nothing happened."

In March 2007 Parry shot and killed an armed ex-convict who pointed a weapon at him and another officer in the city's Whitman Park section. He had been on the force for just six months.

John Williamson, president of Camden Fraternal Order of Police Lodge 1, could not be reached for comment. Parry, Stetser and Figueroa could also not be reached for comment.
