Lamb of God (Randy Blythe is third from the left)

Lamb of God rocker Randy Blythe has been cleared of contributing to a fan's death by pushing him offstage at a gig in the Czech Republic.

The frontman was in the Municipal Court in Prague on Tuesday to hear the verdict delivered, but he faces more weeks of uncertainty as prosecutors lodged an immediate appeal against the ruling.

Blythe spent more than a month behind bars in Prague last summer after he was accused of contributing to the death of 19-year-old fan Daniel Nosek by pushing him offstage at a gig in the city in 2010.

Nosek later died after two weeks in a coma due to head injuries.

The singer was subsequently allowed to go home to the U.S., but returned to the Czech Republic last month (Feb13) to deny a charge of manslaughter on the first day of the trial, and on Tuesday a judge ruled the rocker's actions did not constitute a crime.

Before the decision was announced, Blythe told the court, "I would like to thank the family of Daniel Nosek for not attacking me in the press and for their kind words to me in this court. I am very sorry for their loss. Daniel was a fan of my band. I had no wish to harm him. He was just a boy and I wish he was still here.

"If I am to remain free, I will do my best to insure (sic) that conditions at this concert will not occur again with my band and other bands so that the fans will remain safe. I have searched for an answer to this situation. The only one I can find is that it was a tragic, horrible accident."

Blythe took to his page on image sharing website Instagram after the verdict to thank his fans for their support and to reach out to Nosek's family.

In a post, he writes, "I have been found not guilty & acquitted of all charges against me. I am a free man. Please remember the family of Daniel Nosek in your thoughts & prayers in this difficult time. I only wish for them peace. Thank you for your support."
