Nassau County police are searching for a man armed with a large knife who they said tried to rob a BP gas station in Merrick late Friday.

Around 11:40 p.m., a male suspect wearing a black jacket, black pants, black gloves and a black mask approached the front door of the gas station at the corner of Merrick Road and Newbridge Road and demanded the lone employee inside give him all the money in the store, police said in a news release.

The victim was able to push the suspect out of the way and lock the door without handing over any money, police said. The man fled northbound on Newbridge Road.
