NEWARK -- Police are investigating a shooting outside a Newark funeral home Wednesday morning while a viewing was being held for a 22-year-old East Orange man found dead with a gunshot wound in Newark last week.

Newark Police are investigating a shooting Wednesday morning outside Cotton Funeral Service

Tyshone Overstreet, 21, of Irvington, was arrested in the 11 a.m. shooting outside the Cotton Funeral Service home on Bergen Street.

No one was hurt, and Overstreet was charged with possession of a handgun, police said.

The viewing was for Navis Treadwell, 22, of East Orange, who authorities said was found dead in his car at 6:45 p.m. on March 6, after it crashed on Hawthorne Avenue in Newark. Treadwell had been shot, authorities said.

Newark police said it was uncertain whether the shots fired Wednesday were related to Treadwell's viewing or to a group of men who were outside arguing across the street from the funeral home.

A person who answered the phone at the funeral home on Wednesday declined to comment.

Police asked anyone with information about the shooting to call the department's anonymous tip line at 877-695-8477 or 877-695-4867.
