Police are looking for a man who they say robbed three subway passengers at gunpoint this month.

Investigators say the man, pictured above, walked up to his victims on the A train during the morning rush, showed a gun and robbed them before getting off the train.

Police say none of the victims were hurt during the robberies.

The most recent incident happened Sunday when police say he stole a laptop from a 19-year-old woman and got off the train at the Shepherd Avenue station in East New York.

He is also accused of robbing a man on August 1 and another woman on August 15.

In both of those cases, he took the victims' iPhones and got off at the 80th Street station in Ozone Park.

"You gotta be nuts. There's always cops on this station. Always cops on this station. And to hold people up is ridiculous," said one A train rider.

"I always observe people. I look around and see who's sitting next to me or who's coming through the train, always try to observe," said another.

The man is described as being between 20 to 25 years old and nearly six feet tall.

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
