The former chief of one of the country's largest suburban police departments has pleaded guilty in New York in the beating of a suspect who stole sex toys and pornography from the officer's SUV.

Former Suffolk County Police Chief James Burke pleaded guilty Friday on Long Island to violating civil rights and conspiracy to obstruct justice. It was part of a plea agreement with prosecutors.

He is expected to get over four years in prison. His sentencing has not yet been scheduled.

The 51-year-old Burke was arrested in December. He is being held without bail.

Burke could have faced up to 20 years in prison if convicted at trial.
