An autistic man died after he got into a fight with an employee outside a disability center in Harlem on Friday, sources said.

The man, 33, allegedly attacked a 54-year-old female staffer at Quality Services for the Autism Community (QSAC) on East 129th Street shortly before 5:45 p.m., according to the sources.

He was found unconscious when cops arrived, according to police, who said he’d been restrained by staffers at the center.

EMS rushed the man to Harlem Hospital where he later died, police said.

The staff worker was also taken to the hospital in stable condition.

It is unclear what sparked the spat.

QSAC, with locations across the Big Apple, is a non-profit that provides support services for children and adults with autism.

The man’s identity is being withheld until the family is notified.

The city’s medical examiner will determine his cause of death.
