#Dozens more subway windows smashed hours after MTA offers $10K reward

New York’s serial subway window smashers are apparently undeterred by MTA’s $10,000 reward for information leading to their arrest.

Transit workers reported another 39 broken windows in two separate incidents on the 7 train on Monday — just hours after the MTA announced the bounty, according to the agency.

Workers spotted the cracked glass — 19 windows at 5:22 p.m. and another 20 at 8:51 p.m. — at 34th Street-Hudson Yards station, the 7 train’s Manhattan terminus.

Video from the crime scene by one subway operator shows a trail of car windows with multiple cracks.

“Ok now I’m really concerned for the safety of the #TrainCrews on the 7 Line,” the worker, who uses the Twitter handle @TripleG_RTO, posted along with the video.

“[Enough] is enough its time to catch this guy before he #Hurts somebody.”

The incident brings the total number of windows smashed since May to around 450 and the total cost of repairs to over $300,000, according to the MTA.

Monday’s vandalism added another $19,500 to that total, agency spokesman Tim Minton said.

There have been 70 window-smashing incidents on subway cars since May 8, the MTA said Monday. The trail of destruction has been so extensive that the agency is on the verge of running out of glass.

Police and transit officials remain tight-lipped about whether they think the crimes are being committed by one person or a group of people.

The repeated acts of vandalism have led to hundreds of delays, according to internal MTA records.

The NYPD is offering another $2,500 on top of the MTA’s bounty.

“It’s important that we have the public’s assistance here” in nabbing the suspect, NYPD Transit Chief Edward Delatorre told reporters Monday.

“There has to have been some witnesses to this vandalism over the last couple of months.”
