SUNSET PARK (WABC) -- Officers slammed a pregnant woman to the ground and another woman is shoved in a shocking video now under investigation by the NYPD.
The video is hard to watch.
It shows what happened during an arrest in Brooklyn over the weekend.
A witness posted it on Facebook and it's gotten the attention of the police department's Internal Affairs Division.
Residents she's nearly six months pregnant.
The cell phone video starts with a young man sitting on the street in handcuffs surrounded by police.
His pregnant mother tries to intervene, "Don't resist! Don't resist. Throw your hands up."
The woman who is nearly six months pregnant struggles with police, and as they tried to restrain her Saturday morning she hit the ground onto her stomach.
"Oh my God she's pregnant," you hear in the video.
A family friend also tried to step in, and an officer shoved her away.
"What we see is a woman who's trying to protect her son, who is being stopped and frisked by police, and she became a victim. Slammed onto the floor," said Dennis Flores, of El Grito de Sunset Park. "Her belly is now with black and blue bruises. She's bleeding and she's having complications."
"It's sad that my reaction is that I'm not shocked. It isn't new in this neighborhood. But it's still enraging, it's saddening," said Jason DeLaguila, a community organizer.
The local police watch group that released the video says the 17-year-old suspect was arrested last year for robbery.
This video comes less than a week after an officer from the same precinct was suspended for kicking a street vender.
Councilman Carlos Menchaca says he's disappointed with the 72nd Precinct.
"This is the second video in a week. It's disgusting. This needs to stop. I spoke with the chief and the captain. We have a systemic problem with this precinct. We need to solve it now," Menchaca said.
The NYPD told Eyewitness News the Internal Affairs Bureau is investigating both cases.
The pregnant woman is expected to talk Wednesday.
