A construction site worker who worked in the cab of a crane hit by a helicopter in south London on Wednesday has told the BBC how he is "still in shock".

Crane driver Nicki Biagioni said it was only because he did not wake up on time that he was not in the cab at the time of the incident.

Mr Biagioni told BBC Essex's Thomas Magill that despite regular helicopter traffic in the area the crash was "something he never thought would happen".
