Updated at 10:32 a.m. ET

(CBS News) Two federal agents were shot Thursday morning in Petaluma, Calif., just north of San Francisco, while serving warrants for Immigration and Customs Enforcement, Homeland Security sources told CBS News.

The agents were transported to a hospital, where they are being treated for non-life-threatening wounds. A third agent also received minor injuries in the incident.

ICE released a statement saying a suspect was in custody. The agents were executing "high risk federal warrants" for an ongoing criminal investigation, according to the agency.

The general manager of a Best Western hotel near the incident told CBS Radio station KCBS-AM on air that a loud bang and gunshots were heard around 4 a.m. PT. At least 10 shots rang out, a neighbor told the station.

In a separate incident in southern California, an ICE agent was found dead of a single gunshot wound, and his 14-year-old son was arrested in the shooting, according to a spokeswoman for the Los Angeles County Sheriff's Department, which is investigating the incident.

The federal agency has not released the name of the agent, who lived in Carson, Calif.
