A 39-year-old San Jose man who is suspected of leaving a threatening phone message for Chicago Mayor Richard Daley was arrested by police, according to police and media reports.

Christopher Traynor Fox, 39, was taken into custody Thursday afternoon at his home in San Jose based on an arrest warrant issued by Chicago police and booked into Santa Clara County Main Jail, according to Dirk Parsons, a San Jose police spokesman.

Chicago police say Fox is wanted on suspicion of making telephone threats against a public official, but would not name the official. The Chicago Tribune, citing sources, said Fox is suspected of leaving a threatening telephone message for Daley.

An arrest warrant sought by Chicago detectives was issued Tuesday, according to Chicago police. Cook County prosecutors will request extradition, police said.

Chicago police did not provide additional details, saying the case remains under investigation.

The Mercury News could not reach Fox's mother for comment.

However, she reportedly told Chicago-based WGN-TV on Thursday that she thinks the threat had something to do with Daley's gun-control remarks last week.

Daley spoke at a news conference about what would happen if the U.S. Supreme Court overturns Chicago's handgun ban. Asked by a reporter whether the ban has been effective considering the city's spike in gun violence, Daley picked up a nearby rifle and said: "It's been very effective. If I put this up your butt, you'll find out how effective it is. Let me put a round up your, you know," a chuckling Daley said.
