EDGEWOOD, MD—Maryland State Police arrested an armed robbery suspect following a traffic stop on Wednesday in Harford County.

The suspect, Lavonta Graham, 27, of Baltimore, was initially charged with possession with intent to distribute marijuana following the traffic stop. A warrant check conducted by troopers discovered that Graham was wanted on a violation of probation bench warrant from a 2010 armed robbery/home invasion in Baltimore County for which he pleaded guilty in 2012, along with first-degree assault, second-degree assault, reckless endangerment, illegal possession of a firearm, and armed robbery in Baltimore City.

At just before 3:15 p.m. on February 5, troopers were on patrol in the area of Brookside Drive at Treetop Drive in Edgewood. According to a preliminary investigation, troopers saw a Honda Accord with illegally tinted windows speeding in the area, which led to a traffic stop of the vehicle.

During the traffic stop, a probable cause search was conducted and suspected marijuana was found. Two others inside the vehicle were charged on a civil citation for possession of marijuana.
