'Our world changed immeasurably after son's death'

The father of Barnaby Webber, who was killed last year, says the "world changed for us unmeasurably" on the anniversary of the Nottingham attacks.

Valdo Calocane killed Barnaby Webber, 19, from Somerset, and Grace O'Malley-Kumar, 19, from north-east London on 13 June along with school caretaker Ian Coates, 65.

Mr Webber's father David and his family, along with Ms O'Malley-Kumar's family retraced their footsteps from the night they were killed and laid tributes earlier.
