Two sought in connection with armed robbery investigation in Md.

An investigation is ongoing after deputies say two men were involved in an armed robbery at a Queen Anne's County convenience store.
The Queen Anne's County Sheriff's Office says on Thursday, around 3:50 AM, units were dispatched to the 7-11 convenience store on Pullman's Crossing Road for an armed robbery complaint. Deputies say two men went into the Grasonville store and held the clerk at gunpoint. Investigators say the suspects pointed a gun at the clerk and ordered the clerk to the store's office. The suspects then reportedly tried to bind the clerk's hands.
According to the report, the armed suspects assaulted the clerk by hitting the individual in the head. Law enforcement says two individuals then entered the store while the suspects were tying the clerk's hands. At that point, deputies say the suspects confronted the two individuals at gunpoint while attempting to flee. The two individuals were not injured during this incident.
The suspects were reportedly driving a black truck and remain at large. Authorities continue to investigate this incident.
