WARREN -- City police are investigating an armed robbery Thursday night at the BP gas station at 1290 E. Market St.
Police were called to the gas station just before 11 p.m. and initiated a search involving the K9 unit, but were unable to locate the gunman.
An employee told police she was standing behind the counter speaking with a customer when the male came into the store wearing a ski mask, according to a Warren police report. The report states the assailant pointed a revolver at the employee and ordered her to give him all of the money.
The gunman ran away and headed southwest.
Police said they received surveillance video from the store.
