A Norwalk woman was charged with being the lookout for a second perpetrator still at large who was attempting to steel rims and tires off cars at the Ledge Road BMW dealership, according to Darien Police Sgt. Jeremiah Marron, a spokesman for the department.

Jamila Pereira, 31, of Oakwood Avenue, was charged with third-degree criminal trespass, possession of burglary tools, and conspiracy to fourth-degree larceny, Marron said. In addition, she was charged with illegal possession of narcotics and possession of drug paraphernalia, Marron said.

Police responded to an automatic burglar alarm at the dealership at about 3 a.m. Monday, Sept. 21, and found Pereira sitting in a grey Dodge Charger in an adjacent lot next to Whole Foods Market on Ledge Road, Marron said.

Pereira told officers she had an argument with her boyfriend, but couldn’t explain why she was in the lot, Marron said.

Police detained her, and she later admitted she was helping a man try to steel rims and tires, Marron said. In her car, police found cinderblocks, tools and blankets that appeared to be for targeting jacked-up vehicles, Marron said.

Police found three suboxone patches, a spoon, an unidentified orange pill and a pad of copper Brillo in the Charger, resulting in the drug and paraphernalia charges, Marron said.

She posted $50,000 bond, and was to appear in state Superior Court in Stamford, according to Marron.
