IRA gunman 'seen with gun' on Bloody Sunday

A youth who spotted an Official IRA gunman on Bloody Sunday was going to throttle the would-be assailant, the Saville Inquiry has been told.

The claim was made by Patrick Doherty as he gave evidence in the Guildhall, Londonderry, about the first Army gunfire of the day which ended with 13 Catholic men shot dead.
