OAKLAND — A 15-year-old gang associate was in critical condition Friday after he was wounded twice by his own gun during a struggle with a 32-year-old he pointed the weapon at, police said.

The man, who police said was a former paratrooper in the Honduras army, was not hurt and waited for police to respond to where the confrontation happened. He gave a statement to investigators before he was arrested on suspicion of assault while the district attorney's office determines whether he acted in self-defense.

Police would not release the name of the teen or the adult pending the district attorney's review.

The shooting happened just before 2 a.m. Friday in the 3700 block of Foothill Boulevard in the Fruitvale district. The area is a known hangout of certain gang members and police said the 15-year-old is associated with the gang.

The man was on his cell phone when he was confronted by the teen, and possibly some other youths, said Officer Robert Trevino, who is investigating the case with Sgt. Drennon Lindsey.

The teen pointed a pistol at the man, who had never seen him before, and used a street term to see if he was in another gang, police said. Police said the man is not a gang member and has only been in Oakland eight months, seeking work.

When the teen was momentarily distracted by a passing car, the man grabbed the gun and the two began struggling over it, Trevino said. During the struggle the gun went off twice, hitting the teen in the neck and shoulder, police said.

He was taken to a local hospital by friends where he underwent surgery. The man waited for police to come to the scene and gave them the pistol.

In an unrelated shooting, four people were wounded about 5:20 p.m. Thursday in the 9300 block of Sunnyside Street. A man was shot in the leg and three women were wounded in the back. A man and woman were seen fleeing from the scene, the man on foot and the woman in a vehicle.

None of the wounds were said to be life-threatening. Police had no motive in the shooting and no arrests had been made.

Police and Crime Stoppers of Oakland are offering up to $20,000 in reward money for information leading to the arrest of the suspects in the shooting of the four people. Anyone with information can call police at 510-238-3426 or Crime Stoppers at 510-777-8572 or 510-777-3211.
