West Ham face further security woes after three youngsters broke into the Olympic Stadium to film a YouTube video.

The Hammers moved to their new home this summer but the switch from Upton Park has been tarnished by poor stewarding and numerous altercations in the crowd.

Problems have worsened after three youngsters were allowed to enter the stadium through an unlocked door on the perimeter before climbing up onto the roof, playing on the pitch and sitting on the substitutes bench.

The video was posted to the YouTube channel Night Scape with the break-in starting at (4:01)

Supporters will be concerned at the apparent lack of security measures in place at the stadium in a time when the threat of terrorism remains high.

The on-going security issues at the ground comes during a dismal period on the pitch for the Hammers.

Slaven Bilic’s side have lost five out of their seven league games this term, with their only points coming  in a 1-0 victory over Bournemouth in August and Saturday’s 1-1 draw with Middlesbrough.

Bilic will cut a frustrated figure after he drove West Ham to a thrilling seventh placed finish in England’s top-flight last term and got the best from a side which finished 12th previously.

West Ham now face Crystal Palace and Sunderland, before taking on Chelsea in the League Cup.
