SANFORD, Fla. -- A prosecutor says George Zimmerman's girlfriend claims he choked her about a week ago but she didn't report it to police at the time.

The prosecutor told a judge about the allegation during a first appearance Tuesday on domestic violence-related charges of aggravated assault, battery and criminal mischief.

The judge set George Zimmerman's bond at $9,000 and ordered that he not possess guns or ammunition. He was ordered to stay away from the girlfriend's house and wear a monitoring device.

Zimmerman was taken into custody Monday after girlfriend Samantha Scheibe told deputies he pointed a shotgun at her during an argument.

In a 911 call, Zimmerman denied pointing a gun at Scheibe.

The 30-year-old former neighborhood watch volunteer was acquitted earlier this year of criminal charges in the fatal shooting of Trayvon Martin.
