A BABY was killed when her mum accidentally pushed her stroller into an open lift shaft on Thursday in a building riddled with violations — sending both of them plunging to the roof of the car several feet below, police sources said.

Mum Aberaqed Al-Rabah was with her six-week-old Areej Ali on the 23rd floor of the New York apartment complex when the lift doors opened and she pushed the stroller in, not noticing the car was stuck between that floor and the 22nd, law enforcement sources said.

The baby girl tumbled only a few feet, landing on top of the lift car. Her mother fell in after her and landed on top of the carriage, police sources told The New York Post.

The weight of the mum and the baby on top of the car caused the lift to plummet to the 17th floor where first responders pulled them both out. Areej was pronounced dead at Coney Island Hospital.

Salah Ali, 70, the infant’s grandfather, said the mother’s in “bad shape.”

“She’s in the hospital. She’s injured,” Ms Ali told reporters at the scene. “She breaks my heart. That was my grandchild.”

Jeff Delacruz, who lives in the building, said his aunt works at Coney Island Hospital and spoke to the baby’s mother.

“She keeps saying, ‘everything is OK. It’s OK. God only gave me my baby for one month’,” Delacruz, 28, said.

“She’s probably traumatised.”

His wife Elizabeth said the lifts are always out of service.

“There’s always a problem with the elevators in this building,” Elizabeth Delacruz, 26, said.

“About a week ago, the same one was out of service. The door just didn’t open. It stayed close.”

Harold Noel, 37, who lives on the same floor as Baby Areej, said he’s shocked.

“They’re real good people …. My wife called me said the neighbour fell down the elevator,” Noel said.

“I took the elevator about 8am this morning and it was shaking a bit but we thought it was just the construction … they never work. Everybody is scared of taking the elevators.”

The Bay Park complex has a “chronic problem” with their lifts according to one of hundreds of Department of Buildings complaints.

There’s one active complaint from September 30 against the lift that killed Areej saying it was not working.

There are another two complaints for the lift from July 17 that have been resolved and a complaint from March 9, 2015 that says the lift is “constantly getting out of service” and “has not been working for two and a half weeks.”

There are 45 lift complaints dating back to 2000 at 3415 Neptune Ave.

The entire complex has hundreds of complaints and violations.

The Department of Buildings is on scene investigating the cause.
