Anne Arundel County police responded Friday night to an armed robbery at the David's Natural Market store in Gambrills.
Police spokesman Justin Mulcahy said officers received a call shortly before 8 p.m. and arrived to learn that a man had entered the store and fired a single gunshot to the ceiling. The man demanded money from the store and took the purse of a store clerk before running away.
Police searched the area using assistance from a K-9 unit and aviation unit, but could not find the man.
Mulcahy said the investigation into the incident is ongoing.
