Army bomb disposal experts were called to assess suspicious packages at Old Trafford following the abandonment of Manchester United's Premier League match against Bournemouth.
Goal understands multiple packages were found at the stadium, including at least one in an executive-suite toilet in the Stretford End.
Around 25 minutes before kick-off, United began evacuating both the Stretford End and the Sir Alex Ferguson Stand in response to a security threat.
At 2.40pm, an 'operation red code' alert was heard over the tannoy at Old Trafford.
United subsequently confirmed that the 3pm kick-off would be delayed after a 'suspect package' was found by a steward in the north-west section of the stadium. Goal sources later confirmed that more than one package was found in the stadium.
But shortly after 3pm, United followed up with an announcement that the match would not go ahead at all on Sunday.
Greater Manchester Police are at Old Trafford with sniffer dogs, while a bomb disposal team has arrived at the stadium to further investigate the threat.
"We are awaiting the imminent arrival of military colleagues to come and support us and establish what exactly we are dealing with," assistant chief constable John O'Hare said.
Update: Bomb disposal experts currently at Old Trafford and conducting assessment of suspicious item found before game.
