(CBS/AP) SEATTLE - A Washington man could face months in jail for punching a 10-year-old boy in the face because the child was being too noisy in a movie theater.

Yong Hyun Kim, 21, was watching "Titanic" in 3-D with his girlfriend when he asked the people sitting behind them to quiet down and stop throwing popcorn, according to the police report, which goes on to say the other movie-goers started laughing at Kim, which made him angry so he swung his arm at the child's face. 

"I got so mad that it just happened," Kim reportedly told police, who arrested him the night of April 11 at the AMC theater in Kent, a south Seattle suburb. He was released the next day.

The 10-year-old lost a tooth and had a bloody nose in the confrontation. Police say Kim told them he thought the person he hit was a grown man.

Kim was charged with second-degree assault on May 16. He could spend three to nine months in jail if convicted, county prosecutor's spokesman Dan Donohoe said.

Kim will be arraigned May 31 at the Regional Justice Center in Kent.

The police report identified the boy as KJJ. He said he was watching the movie with three friends and talking when Kim told them to be quiet. They quieted down, but when KJJ whispered something, Kim jumped over the seat, threw an iced drink at them and punched KJJ in the face, according to the report.

Kim told police the boys' behavior was worse than talking. He said they were also hitting him and his girlfriend with popcorn, running back and forth in the aisle and bumping him with their arms.

AMC Theatres spokesman Ryan Noonan said in a statement that the theater's management told him no one else had complained about audience behavior prior to the incident.

"We strongly encourage guests to be respectful of their fellow moviegoers, and to report any disturbance to an AMC associate, so that we may handle it directly," Noonan said.
