Police are asking for the public's help in identifying the man who robbed and stabbed a convenience store clerk early Monday.

About 4:10 a.m., police said, a man entered the Wawa at 7715 Frankford Ave., then stabbed the cashier in the left arm as she opened the register to ring up a candy sale. The man reached into the register, grabbed $190, and fled, police said. The cashier received several stitches to her arm.

The robber is described as white, about 30, 6 feet tall with a thin build, wearing a navy-and-gray baseball cap. He also was wearing blue jeans and a blue-and-gray jacket with white sleeves.

Anyone with information about the man is asked to call Lt. Mark Burgmann of the Northeast Detective Division at 215-686-3153.
