A teenager suspected of shooting at and stabbing a friend he had been playing video games with Monday afternoon was arrested in Oakley, a Contra Costa County Sheriff's spokesman said.

Oakley police responded to a home in the 1500 block of Yosemite Circle shortly after 1 p.m. day, sheriff's spokesman Jimmy Lee said.

They found a 20-year-old man suffering from multiple stab wounds.

Police also found that the man had been shot at but was not struck by the gunfire.

The man was airlifted to John Muir Medical Center in Walnut Creek and was in stable condition as of Monday evening, Lee said.

Oakley police found a suspect in the case in the 200 block of Chateau Court about 25 minutes later. The 17-year-old ran from police, who chased him through backyards before he was eventually captured.

He was booked into juvenile hall on suspicion of attempted murder.

Lee said that the suspect and the victim were friends and had been in their separate homes playing video games against each other online and got into an argument prior to the stabbing.

According to the victim's mother, the suspect came to their home and she confronted him at the door, telling him he couldn’t come in. But he persisted, pushed her aside and fired his weapon at her son.

He missed, hitting the walls of her home instead.

"He actually had the gun aimed at me, but he shot at my son," said the victim's mother. "I went downstairs to call the police and he ran downstairs, put his gun down, ran back up the stairs and evidently -- I thought they were fist-fighting -- he was stabbing the h*ll out of my son."
