The device which forced the abandonment of Manchester United's Premier League clash with Bournemouth "wasn't viable", Greater Manchester Police have said.
What was supposed to be an important final league match of the campaign instead ended with fans being evacuated from the ground before kick-off, with players ushered off the pitch during the warm-up.
A security alert in the stadium's North West Quadrant led to spectators in the Stretford End and Sir Alex Ferguson Stand being evacuated from the ground, before the remaining fans were told to follow as the match had been abandoned due to a security alert.
Bomb disposal exerts carried out a controlled explosion on a suspect package just after 4.30pm and Great Manchester Police later announced in a statement on Twitter: "Bomb disposal experts carried out a controlled explosion at Old Trafford on what is described as (an) incredibly lifelike explosive device.
"Full assessment now concluded and found device wasn't viable. A full search of the stadium is ongoing. Full update to follow."
