A failed robbery turned into a failed arson Saturday morning at a Brooklyn check-cashing store.

Police are looking for a man who walked into the Pay-O-Matic on Rockaway Avenue in Brownsville at 10:30 a.m. and demanded cash. When the clerk refused to cough it up, the suspect took out a bottle of gasoline and poured it on the floor, police said.

He threatened to torch the place. And a moment later, lit a match and dropped it on the floor.

When the gas failed to ignite, he fled.

The NYPD released surveillance camera images of the suspect, who is approximately 5-feet, 10-inches tall and was wearing a pink baseball hat and carrying a large duffle bag at the time of the incident. 

Anyone with information is asked to call the NYPD Crime Stoppers Hotline at (800) 577-TIPS.
