Falls police are investigating three robberies in the city that are believed to have been committed by the same suspect.
The first robbery occurred Monday afternoon at a gas station on the 500 Main Street.
At about 8:40 p.m. Monday, police responded to a second robbery at a convenience store at 29th and Pine Avenue.
In both cases the suspect was wearing a bag over his head and a plastic bag over his body and hands and appeared to be holding a handgun. Following the convenience store robbery, the suspect ran south through the 600 block alley between 28th and 29th streets where officers found the items he used as a disguise.
A Niagara County Sheriff’s K-9 was called in to assist in a search but police couldn’t locate the suspect.
Late Monday night, police said the same suspect was believed to have robbed a donut shop on the 700 block of Portage Road.
Those with information are asked to call Niagara Falls Police at 286-4547.
