LANHAM, Md. (CBSDC) — Phony utility workers have scammed at least two households in Prince George’s County, police say.

Prince George’s County police believe the same suspects are responsible for the two incidents, both of which occurred in Clinton.

The first scam happened Oct. 30 in the 6500 block of Horseshoe Road. Police say two suspects wearing hard hats told a homeowner they worked for the water company and needed to check on a gas leak in the person’s home. When the homeowner walked into a bathroom with one suspect, the other suspect stole cash and a safe. The homeowner told police the scammers were driving a dark-colored sedan.

The second scam happened Nov. 6 in the 5800 block of Kirby Road. The suspects, who posed as contractors and dressed in phony uniforms, told the homeowner that they were conducting survey work in the area. When the homeowner walked with one suspect to the rear of the home, the other suspect entered the home through the front door and stole a safe.

Police say no one was hurt in either incident.

A third scamming attempt in Upper Marlboro proved unsuccessful when the homeowner became suspicious and the suspects fled.

Prince George’s County Police say most utility workers do not need access to a customer’s home, and utility workers are required to wear uniforms and drive vehicles that are clearly marked. They are also required to wear work badges where it’s visible to customers, and the worker should also be able to provide his or her supervisor’s name and contact information.

Police say if for any reason you are still unsure of the individual’s identity, call the utility company for confirmation as well as the police.

Anyone with information on these cases is asked to call Crime Solvers at 1-866-411-TIPS (8477) or the Regional Investigation Division – South at 301-856-3130.
