Cops in New Milford, New Jersey are looking for a man who posed as a cop to rob a carload of teens.

The teens reportedly told police the suspect stopped them on New Milford Avenue right before 6 Friday night and told them he was a detective and he saw one of them rolling a joint. He then demanded to know, "Where is the pot?"

Then, cops say he told the 17-year-olds to get out of the car, take off their shoes and empty their pockets. Next, he searched the car and stole $110 from the glove compartment.

The teens say the driver of the car reached for his cell phone to call his parents, but the would-be cop fought it away from him, then got back in his car and drove away.

The suspect is described as a muscular white man, believed to be in his mid-20s, about 5'9 and 210 pounds, with short brown hair and light-colored eyes. He was driving a dark gray, four-door Toyota. The teens are not sure if it was a Camry or Corolla, and they say it had a smudged license plate that includes the letters MP.

If you have any information that might help cops find this suspect, they ask that you call New Milford police at (201) 599-7567

Police Chief Frank Papapietro told the Cliffview Pilot newspaper that all police officers are required to carry a department ID card.

He also says, "Please, if you are suspicious of a non-uniformed police officer, contact your local police department or request from the person that a marked unit be dispatched."
