An alleged gang member has been shot dead in a US courtroom after apparently 'lunging' at a witness who was testifying against him.

Siale Angilau, 25, was not handcuffed and was shot a number of times by a US marshal after he was said to have made an "aggressive" move toward the unnamed witness while holding a pen.

The shooting took place in a new federal courthouse in Salt Lake City, Utah. No one else was injured in the incident, the FBI said.

Mr Angilau - who faced a string of charges relating to alleged street crime - was taken to hospital after the shooting where he later died from his injuries.
