NEW YORK (CBSNewYork) — An 8-year-old boy accidentally shot himself in the head Monday inside a Bronx home.

Police said the 9 mm belongs to Rajon Grant, the boy’s 43-year-old father, and is unlicensed. Grant was not home at the time and the gun was in a safe in his bedroom on a top shelf in a closet. Police said the boy likely had to climb to get the gun, but it’s not known if the safe was locked.

After being questioned at the 52nd Precinct throughout the day, Grant was arrested and charged with criminal possession of a weapon and endangering the welfare of a child.

Police said the boy was in critical but stable condition.

Cellphone video showed an ambulance at the Fordham Hill Cooperative Apartments, where the 8-year-old was put inside.

A next-door neighbor said he didn’t hear the shot, but the boy’s younger siblings banged on his door frantically.

“They were screaming, crying, yelling, telling me to come next door,” neighbor Eric King said. “The mother is yelling, screaming, panicking a little bit. Understandably, though, the kid got shot. I saw the kid on the floor with his eyes open, not breathing and blood everywhere.”

The boy’s father came rushing back and drove his car into the front security gate.

“Upon hearing about it, he came to the gate and as you can see the fence is down. He tried to rush in, tried to get to the apartment,” Councilman Fernando Cabrera.

Cabrera, who lives in the complex, said he watched the child go into the ambulance and then later shared an update.

“He is expected to recover. The good news is that the bullet did not penetrate the skull, so the child is going to make it,” Cabrera said.

Residents said they could not believe what happened.

“I am sad and shocked because you never hear anything that tragic happening around,” one person said.

“This neighborhood, let’s say our apartment, you don’t regularly hear these things,” another said.

“I’ve been living here for more than 30 years and this is like a little oasis in the Bronx and it’s really shocking to hear that,” resident Tania Pichardo added.

King said he thinks this was a horrible accident.

“The parents are good people, so I’m not thinking anything about guns. I’m not surprised he has one because he’s a night club owner. You know what type of city we live in,” King said.
