The court documents just filed in the arrest of a Baltimore police officer accused of stealing money from a drug dealer (who turned out to be an undercover detective) provide a detailed account of the case.

Authorities say the officer was targeted because of complaints and moved from a drug task force working Pennsylvania Avenue to the Northwest Police District. There, he was put in charge of training a rookie cop (done, police tell me, to avoid tipping the officer that he was under suspicion). The rookie is not in any trouble.

Members of the department's Internal affairs Integrity Unit set up the sting for Thursday night in the 3900 block of Carlisle Ave., in an area normally devoid of drug dealers. At 9:45 p.m., an undercover officer parked a green Cadillac at Carlisle and Mt. Holley Street while another officer called 911 and described a suspicious green vehicle driving around the block, supposedly looking to buy drugs.

At 9:48 p.m., a dispatcher sent Officer Michael Sylvester (in picture) to the call and told him a person was sitting in the Cadillac for 15 minutes and "acting strange." At 9:50 p.m., court documents say Sylvester pulled up beside the vehicle and shouted, "What are you doing here?" The undercover officer answered, "I'm waiting for my home boy to come meet me."

The court documents say Sylvester ordered the driver to turn off his ignition, turn over his license, get out of the car and sit on the curb. The man gave Sylvester permission to search the car and he emptied his pockets onto the front seat of the car. The charging papers say Sylvester conducted the search alone. After the search, court documents say Sylvester told the driver he was free to go and drove off.

Police say that the uncover officer had $259 in marked bills in his pants pocket and an additional $135 in marked bills in the arm rest of the Cadillac. After Sylvester and the training officer left, the undercover says in court documents that $50 was missing from the money that was in his pocket and $20 was missing from the money that had been in the car.

Undercover police officers followed Sylvester through the remainder of his shift, which ended at 11 p.m. They stopped Sylvester in the parking lot of the Northwestern District after he had changed into civilian clothes and was about to get into his personal vehicle. A lieutenant escorted the officer to an office while detectives searched his locker and reported, according to the charging documents, finding three blue zip lock bags containing suspected cocaine in the breast pocket of his uniform.

Police say Sylvester, 29, is being charged with theft and drug possession.
