Police in two Lowcountry communities are investigating a pair of armed robberies that occurred at Kangaroo convenience stores this morning.

Charleston police are probing a holdup of a Kangaroo store at 1805 Savannah Highway that took place at 2:12 a.m. Two men walked into the store, displayed a pistol and forced a clerk to hand over $118 in cash, police said.

Both men dressed in black and wore masks, police spokesman Charles Francis said. One robber was said to be about 5 feet 11 inches tall and the other was 5 feet 8 inches tall. No other description was provided by police. The men ran off after the robbery and remain at large.

North Charleston police were called to another Kangaroo store at 6923 Rivers Avenue at 8:20 a.m. Two men had run in the store. One jumped over the counter and the other ran to the cooler to retrieve the clerk. One man had a foot-long knife, according to a police report.

The men forced the clerk to hand over about $50 and then fled, police said. No one was injured, police spokesman Spencer Pryor said.

The robbers were said to be around 25 years old. They wore caps and covered their faces. One was about 5 feet 10 inches tall; the other, 6 feet 3 inches tall, police said.

Investigators have not established a link between the two crimes but are probing for possible connections, Pryor said.
