The police and crime commissioner for Greater Manchester has called for a full inquiry into the "fiasco" that saw Old Trafford evacuated over a fake bomb ahead of a Premier League match.

The call by Tony Lloyd came after it emerged the security alert was caused by a training device left by a private company.

"It is outrageous this situation arose and a full inquiry is required to urgently find out how this happened, why it happened and who will be held accountable," Mr Lloyd said.

Mr Lloyd, who is the interim mayor of Greater Manchester, called the situation "unacceptable", but said it "in no way demeans the professionalism of the police and stewards responsible for getting fans out, or the supporters' calmness and cooperation during the evacuation".

The evacuation was triggered by the discovery of what police described as an "incredibly lifelike" device in the stadium toilets.

Spectators were moved out of Old Trafford about 20 minutes before the scheduled kick-off of time after an announcement was made for security personnel to invoke "operation red code".

The match was subsequently called off.

Army bomb disposal experts carried out a controlled explosion on the device in the North West Quadrant of the ground at 4.30pm.

Assistant Chief Constable John O'Hare from Greater Manchester Police (GMP) confirmed the item was a "training device which had accidentally been left by a private company following a training exercise involving explosive search dogs".

Mancherster United's game against Bournemouth has been rearranged for Tuesday at 8pm.
