After two store robberies in the Bel Air area Friday, a gas station in Rock Spring was robbed Saturday.

Investigators charged a 30-year-old Bel Air man with the robbery of the Sunoco on Rock Spring Road, near the Rock Spring Shopping Center by the Bel Air Bypass, shortly after the incident, according to a press release from Maryland State Police early Monday evening.

Luke Raymond Johnson, of the 800 block of Chesney Lane in Bel Air, allegedly entered the station at about 1:30 p.m. on Saturday and demanded cash.

When the station employee hesitated, Johnson allegedly pulled out a box cutter-style knife from his pocket and threatened the clerk with the weapon, according to the release.

Johnson ran out of the store and was seen wearing gray jogging pants and a dark sweatshirt and covered his face with a white cloth.

After police arrived, several witnesses told troopers they saw a man flee the store and drive away in a van with the placard displaying a construction firm's name.

Investigators researched the construction firm and spoke with company representatives, who gave the employee's information and the possible location for the company's vehicle.

Johnson was found at his home, wearing the same clothing described by the store clerk. He was arrested without incident.

During the investigation, troopers also recovered drug paraphernalia with what is suspected to be heroin and the knife described by the store employee.

In addition to armed robbery, Johnson is also charged with first- and second-degree assault, theft less than $1,000 and drug violations.

At a bail review hearing Monday, District Court Judge Victor Butanis ordered him to continue being held on $250,000 bail.
