A subway rider in New York was punched on her way to work after complaining about a man who was taking up too much space, the woman said.

The incident happened as Sam Saia headed to her job in Manhattan from her home in Brooklyn around 7:45 a.m. on Thursday, she wrote on Facebook. She claims a man who sat next to her spread his legs and pressed her against the wall.

The man called her vulgar names when she asked him for more room, she wrote.

She put her ear buds in and told the man to relax. He told her not to ignore him and punched her in the face, banging her head against the wall, she said.

“A bunch of good people ran to help me, as my lip was gushing blood,” Saia wrote. She posted a photo of her bloodied lip on Facebook.

Saia also later posted a video of a man she said came to her aid and kicked her assailant off the train.

“Get off the train, bro!” the man said to the other. “You don’t hit a lady.”

Saia did not immediately respond to a request for comment.

The man who shot the video, Anthony Macca, said in a phone interview that he had seen the two arguing for about five minutes before the woman was hit.

A spokesman for the New York Police Department said Saia’s complaint was being investigated. The Daily News reported it is also investigating whether any officers violated department rules in allegedly resisting her request to make a report.

The man who came to Saia’s aid, Victor Conte, told the newspaper that he sprang into action from the other side of the car after seeing the altercation.

“I was mad that he hit her and no one else on the train did anything,” he said. “There were two guys literally sitting across from her and they just looked away.”
