PRAGUE – The frontman of the U.S. heavy metal band Lamb of God has been released from a Czech prison on $400,000 bail as police investigate him for allegedly pushing a fan off a stage who later died of his injuries, an official said Friday.

A Prague court on Thursday dismissed a prosecution request that Randy Blythe be banned from leaving the country. Blythe's lawyer, Martin Radvan, said the singer had flown out of the Czech capital for the United States on Friday. The band is based in Richmond, Virginia.

"I'm relieved to be out of Pankrac jail," Blythe told the private Czech Nova television at Prague's international airport. "It wasn't bad but it wasn't exactly fun."
