MIDTOWN, Manhattan (PIX11) — A woman who was slashed on a Manhattan subway platform Monday night was attacked while trying to assist another woman, police said Tuesday.

At about 6 p.m. at the 34th Street-Herald Square station, a man approached a 33-year-old woman and slapped her phone out of her hand. He then picked up the phone and attempted to run away, police said.

That’s when a 27-year-old woman tried to step in. Police said she tried to assist the first woman by attempting to stop the thief from fleeing. That’s when he slashed her with an unknown weapon, causing a puncture wound.
