Randy Blythe, lead singer of the US heavy metal group Lamb of God, has been acquitted of manslaughter following the death of a fan at a 2010 concert.

Blythe, 42, was accused of causing the death 19-year-old fan Daniel Nosek after he pushed him off stage at a Lamb of God concert at the Club Abaton in Prague in May 2010.

Nosek hit his head as he fell to the ground and died of his injuries several weeks later.

A court in the Czech republic has ruled that the singer's actions did not constitute a crime and he has been acquitted of the charges against him.

Blythe was arrested at Prague airport as the band returned to play another gig a year after the performance at Club Abaton. The 42-year-old did not know Nosek had died of his injuries at that time.

He spent five weeks in a Czech prison while prosecutors debated the value of his bail. After being released, he went back to the US but returned to the Czech Republic for the opening of his trail.

The singer denied manslaughter. He 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, ultimately the Czech legal system sentences me to prison, I will do my sentence like a man.

"If I am to remain free, I will do my best to insure 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."

Following his acquittal, Blythe has posted the following statement on his Instagram account: "I have been found not guilty & acquitted of all charges against me. I am a free man. This photo [See below] was taken by my friend @aceyslade - it says it all.

"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 - Randy".

Blythe faced up to 10 years in prison if he was found guilty.

Lamb of God formed in 1990 and have sold more than two million albums worldwide.
