Lamb of God rocker Randy Blythe has returned to court in the Czech Republic, where he is accused of contributing to a fan's death by pushing him offstage at a gig in Prague.

The singer, who spent a month behind bars while he was remanded in custody last summer (12), faced the family of teenage fan Daniel Nosek in court on Monday (04Mar13) as the trial resumed.

Experts, who carried out psychological tests on Blythe last summer, testified that the singer does not suffer from a personality disorder, thus contradicting a previous assessment by a court-appointed criminal psychologist, who characterised the singer as someone prone to exhibiting "histrionic and asocial tendencies".

Addressing the court, Blythe appeared to be more than a little shocked when the initial report was translated for him.

He said, "When I was in jail, I was given three tests. One was with some blocks, one was looking at some pictures in a magazine as you told stories... and the other a Rorschach test, which is a very old test."

The court-appointed psychologist stated her tests were very modern.

Prosecutors had, in previous court sessions, called witnesses who described Blythe's onstage aggression, recalling him pinning down one stage invader.

Blythe has no recollection of pushing Nosek off the stage at the show in 2010, but one gig-goer testified that she had witnessed the alleged incident.

She told the court, "He (Nosek) climbed onto the stage, and when he tried to stand up, Blythe shoved him."

Nosek, 19, left the gig with friends but later complained of a headache and started vomiting. He was taken to hospital, where he underwent emergency surgery to reduce swelling on his brain. He fell into a coma and died weeks later.

The trial continues on Tuesday (05Mar13).

If found guilty of manslaughter, Blythe faces up to 10 years in prison.
