JACKSON —A Jackson police officer was arrested on Thursday and charged with interfering in the murder investigation of a man found fatally shot at a defunct township restaurant, authorities said.

Eric Prosniewski, 45, of Jackson, was charged with two counts of hindering apprehension for giving detectives from the Ocean County Prosecutor's Office false, deceptive and misleading information in the investigation of the death of Peyman Sanandaji at the former Casanova Ristorante, Ocean County Prosecutor Joseph Coronato said.

Sanandaji, 34, was found shot to death inside the restaurant shortly after 11 p.m. on April 9.

Coronato said Prosniewski is friends with Daniele Romeodisantillo, one of the two men charged with killing Sanandaji, at the time of the murder. He said Prosniewski was not on the job when the alleged interference occurred.

Coronato would not specify how Prosniewski allegedly hindered the investigation.

Al Della Fave, spokesman for the prosecutor's office, said Prosniewski was arrested shortly after 4 p.m. at Jackson police headquarters.

Bail for Prosniewski was set at $100,000, with no 10 percent alternative.

Authorities arrested the first suspect, Hector Calderon, 47, of Freehold, the day after the shooting. Coronato has said investigators determined that Sanandaji was allegedly shot during the course of an altercation with Calderon.

Romeodisantillo, 27, of Manalapan, surrendered to authorities on April 17. He has been charged with murder, conspiracy to commit murder and possession of a weapon for an unlawful purpose. He was being held at the Ocean County Jail in Toms River on $1 million bail.
