Gunman worked as army security officer for G4Spublished at 00:21
More details have been emerging about gunman Omar Mateen. We now know that he had been working as an armed security officer for the firm G4S since 2007.
Attention has also been turning to his father, Seddique Mateen. Mr Mateen, who earlier said the attack had "nothing to do with religion", has a political television show on a California-based channel, on which issues such as the Afghan Taliban were apparently discussed.
