A Florida man acquitted of murder in the fatal shooting of an unarmed black teenager has been arrested on charges he pointed a shotgun at his girlfriend.
George Zimmerman has been jailed in Seminole County, Florida, the BBC reports.
The 30-year-old was charged with felony aggravated assault, battery, domestic violence and criminal mischief, a sheriff's office spokesperson said.
In July this year, a jury cleared Mr Zimmerman of the February 2012 second-degree murder of 17-year-old Trayvon Martin.
The acquittal sparked a fierce debate about racial profiling and gun culture in the United States.
Since then, reports the BBC, Mr Zimmerman has had other brushes with police, including an incident in October when he was briefly detained following a domestic disturbance at the home of his estranged wife, Shellie.
On Monday, a spokesperson for the Seminole County sheriff's department said deputies responded to an emergency call at a house in Apopka about 12.30am.
Mr Zimmerman's girlfriend said they had argued, and he had broken a glass table in the living room, then retrieved a shotgun and pointed it at her, police said. He then pushed her out the front door and barricaded himself inside.
She was not injured and Mr Zimmerman was not armed when officers arrived and did not resist arrest, police said.
