QUEENS, N.Y. (PIX11) – Police are searching for a woman who allegedly attacked a pregnant woman on the 74th Street station platform in Jackson Heights, Queens on Wednesday.

An argument broke out between the two on the No. 7 train when they bumped into each other, according to authorities. That’s when the fight got physical, and the woman allegedly kicked the pregnant woman in the stomach and hit her in the head with a cellphone, police said.

The suspect took off after the attack, according to authorities. The pregnant woman was taken to a hospital with swelling to her face and stomach pain, but police said she and her baby are expected to be OK.
