Police are searching for a man who shoved a 61-year-old straphanger off a Brooklyn subway platform — just minutes before a train was due at the station. The victim got into an argument with his attacker on a Bronx-bound D train platform at the Atlantic Ave.– Barclays Center station around 11:50 p.m. Saturday, cops said. The man shoved the victim onto the tracks, and as bystanders rushed to pull him back onto the platform before a train rumbled into the station, the attacker took off on foot. The train was scheduled to arrive at the station at 11:52 p.m. Saturday night, according to MTA timetables. The victim suffered a facial wound during the attack and was taken by medics to NewYork-Presbyterian Brooklyn Methodist Hospital. Police are still looking for the shover, and on Tuesday released pictures in the hope someone may recognize him. Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS. ...read more read less
