Two men impersonating police officers robbed a motorist in Southeast Washington early Saturday, police said.

Driving in a dark, 2004 or 2005 Chevrolet Impala, the men turned on a set of dashboard lights and pulled over the victim in the 4800 block of Texas Avenue SE at about 3 a.m., police said. The men were wearing dark-colored vests with the word “police” written across the front and were carrying holstered guns, authorities said.

The men instructed the victim to get out of his car and then robbed him of about $400 before fleeing in the Impala, police said. The victim was not harmed.

D.C. police Capt. Brian Harris cautioned residents about the incident during a Saturday news conference, saying anyone pulled over can ask the officer to show identification. Or, if someone is suspicious about being stopped, Harris recommended calling 911.

Harris said there had not been any reports of similar incidents in the area.

The robbers did not present any badges or other police identification during the robbery, police said.

Police asked anyone with information about the incident to contact the Metropolitan Police Department.
