An arrest has been made in connection with five thefts during the past few weeks in Lexington.

David Nathan Griggs, 35, is accused of robbery after a snatch-and-run at a Family Dollar on Waller Avenue on Wednesday.

During the incident, a man reached across the counter and grabbed some cash, and as he left the store he bit a bystander who tried to stop him, Lt. Roger Holland said. The robber then drove off in a silver sport-utility vehicle. Witnesses provided the license plate number, and police found the vehicle on Waller Avenue on Thursday.

Griggs is also accused of a robbery at a Cricket Wireless store on Versailles Road earlier Wednesday, according to a Lexington police news release. In that case, a robber pretended to buy minutes for his cellphone. When the clerk opened the register, the robber said he had a weapon and stole cash.

Griggs was charged with two counts of first-degree robbery. He also was charged with two counts of first-degree burglary and one count of second-degree burglary at Lexington residences.
