London attack: 'Chaos, screams, something bad was happening'
"There was a lot of chaos, glasses dropping, screams, I knew something bad was about to happen," said a witness to the London terror attack.
Welshman Gareth took the elevator to the first floor with his fiancée, heavily-pregnant friend and her partner and they all hid in a toilet cubicle.
He described seeing a man entering with a machete and his fiancée telling him he was wearing an explosives vest.
Twelve people have been arrested after the attack which left seven people dead and 48 injured.
