Los Angeles police were seeking the public’s help in locating the family of a young boy found alone at Union Station on Wednesday.

The child is nonverbal and possibly autistic, Los Angeles Police Department Sgt. Stout said.

The Police Department initially believed the boy was deaf but Capt. Marc Reina later tweeted that an American Sign Language interpreter determined he could hear.

Authorities were alerted to the unattended child in the transit hub around 7 p.m. Investigators were working to recover surveillance video from the station to track his whereabouts before that.

A young black woman was seen playing with him around 6:30 p.m., but then she grabbed her bags and left, officials told KTLA. It was unknown whether she is related to him.

He was being placed in the custody of Child Protective Services Wednesday night, officers said.

LAPD described the child as about 5 to 7 years old and black with brown eyes and braided, dark-colored hair. He measures around 3 feet 5 inches tall and weighs about 60 pounds.

He was wearing a blue down jacket, white tank top, beige pants and grey tennis shoes when he was found.
