Police are searching for a suspect in an Aspen Hill armed robberyafter a man was held at gunpoint and forced to drive to multiple ATMs to withdraw money earlier this month.

The 20-year-old victim was approached by the robber while sitting in his vehicle at the Leisure World shopping center in Silver Spring at about 8:45 p.m. on Nov. 21, Montgomery County Police said.

The suspect first asked for directions to the Glenmont Metro station, then pulled out a handgun and entered the victim’s car, police said.

Though the victim was told to drive to several ATMs in the Aspen Hill area, he was not able to withdraw money, police said. The gunman then told the victim to stop in the Aspen Hill Shopping Center parking lot, taking his credit card, iPhone and keys before running away. The victim called the police soon thereafter.

The victim’s credit card was later used at a CVS on Veirs Mill Road, police said. Surveillance video from the store shows the suspect wearing a black ski mask and jacket while making a transaction.

The suspect wore a black hooded North Face jacket, dark blue jeans and a skullcap at the time of the robbery, police said.

Police do not believe the incident is connected to other recent armed robberies, said Montgomery County Police spokesperson Officer Janelle Smith.

Anyone with knowledge of the suspect is asked to call the 4th District Investigative Section at 240-773-5530. They can also call Crime Solvers toll-free at 1-866-411-TIPS or contact them online.
