Police are looking for a man who tried to rob two gas stations in Brooklyn, but got away empty handed.

It happened Sunday at two different BP gas stations.

Police say the first incident happened around 11:15 a.m. at the BP gas station on Morgan Avenue.

They say the suspect approached a customer inside the store and placed a gun to his head. Police say the suspect escorted the customer to the register and pointed the gun at a clerk and demanded money. 

But police say when the employee refused the suspect's demands, the suspect tried to grab money from the cash register before running away empty handed. 

The second incident happened around 2:00 p.m. at the BP gas station on Bushwick Avenue.

Police say the same suspect walked into the gas station, approached the counter with a gun and demanded money from the clerk, but the clerk refused and the suspect ran away empty handed. 

The suspect is described as being between 5'9" and 5'10" tall with a medium build and was last seen wearing a black ski mask, blue gloves, a dark-colored hooded sweater, a red shirt, dark-colored pants and dark-colored sneakers.

Anyone with information is asked to call the NYPD's Crime Stoppers hotline at 1-800-577-TIPS.
