An NYPD officer was caught on a disturbing video tackling a clearly pregnant woman and riding her to the ground early Saturday in Brooklyn.

The recording shows Sandra Amezquita, who is 5-foot-4 and five months pregnant, being grabbed by the arm and thrown to the pavement with the cop on her back in Sunset Park around 2:15 a.m. The baby’s father, Ronel Lemos, said he watched in horror as his wife hit the ground belly-first.

“The first thing I thought was they killed my baby and they’re going to kill my wife,” Lemos, 50, told the Daily News on Tuesday.
