NIAGARA FALLS – The rash of armed robberies in the city continued with another armed robbery reported Wednesday. City detectives have been called to investigate nearly half a dozen armed robberies in the city over the past two months.

The owner of a Valero gas station and convenience store in the 1900 block of Ferry Avenue told police that just before 3:30 a.m. Wednesday two men wearing all black and ski masks, one of them armed with a semi-automatic handgun, entered the store and stole the cash register.

The owner said the armed man appeared to have tripped when he entered the store and fired one shot. Both men then picked up the cash register, which contained about $200, and fled west towards 19th Street.
