A private security firm that staged a training exercise which caused a Premier League match at Old Trafford to be postponed has been named.
Security Search Management & Solutions Ltd was hired by Deacons Canines on Wednesday to test its sniffer dogs using fake bombs, the BBC understands.
A device was left behind, leading to the postponement of Manchester United’s match against Bournemouth.
Calls have been made for an inquiry into Sunday’s “fiasco”.
Supporters were evacuated from the Stretford End and Sir Alex Ferguson Stand close to the 15:00 BST kick-off after the device was found in the quadrant between the two stands.
The game was eventually abandoned about 15:15.
A controlled explosion was carried out on the item after it was found by a member of staff in a toilet block.
Deacons Canines, from Llandegfan in Anglesey, hired Kent-based Security Search Management & Solutions Ltd to carry out the sniffer dog training exercises.
Greater Manchester Police and Crime Commissioner Tony Lloyd called for a full inquiry and demanded answers to find out “how this happened, why it happened and who will be held accountable”.
“This fiasco caused massive inconvenience to supporters who had come from far and wide to watch the match, wasted the time of huge numbers of police officers and the Army’s bomb squad, and unnecessarily put people in danger, as evacuating tens of thousands of people from a football stadium is not without risk,” said Mr Lloyd.
“Whilst this in no way demeans the professionalism of the police and stewards responsible for getting the fans out, or the supporters’ calmness and co-operation during the evacuation, it is unacceptable that it happened in the first place.”
