Arrest Warrant Issued for Mindy McCready

An arrest warrant issued for Mindy McCready (search) says the country singer has violated her probation on a drug charge, authorities said Wednesday.

A judge signed off on the warrant Monday because McCready left Tennessee without getting permission from her probation officer and didn't report to the officer during July, according to Williamson County Sheriff's officials interviewed Wednesday.

Authorities said this was McCready's second probation violation, which means she cannot post bond this time and likely will have to serve time in jail.

The probation violations stem from charges brought against the singer last year, when she pleaded guilty to fraudulently obtaining the painkiller OxyContin (search) at a pharmacy in Williamson County. She was fined $4,000, sentenced to three years of supervised probation and ordered to perform 200 hours of community service.

McCready violated her probation on May 6 when she was charged with driving under the influence in Nashville. She posted a $5,000 bond in Franklin, according to sheriff's records.

A few days later, McCready's boyfriend, William McKnight (search), was charged with attempted murder after allegedly breaking into her home and beating her.

Last month, McCready was released from a Florida hospital after an apparent suicide attempt at an Indian Rocks Beach hotel, authorities said.

The 28-year-old singer had a No. 1 hit in 1996 with "Guys Do It All the Time."
