British authorities said Sunday that a suspect device they found at the Manchester United stadium and detonated was not viable.
Manchester police described the device as "incredibly lifelike," and that a full search of Old Trafford stadium was being conducted.
After the device was found, tens of thousands of fans were ordered evacuated from Manchester United's 75,600 capacity stadium just 20 minutes before kick-off against Bournemouth in the final Premier League match of the season.
The match was initially delayed with the discovery of the package, but then called off.
British military bomb disposal experts took control of the suspicious package, which was found in the stands, and exploded it.
A European security official said the discovery of the package at Old Trafford coincided with increased Internet chatter about threats to sports stadiums where there are large crowds.
Security at Premier League matches was increased after terrorists in Paris killed 130 people last November, including at the Stade de France sports stadium during an international match.
There has been no announcement about when the Manchester United-Bournemouth game will be played. The result would at minimum have an impact on prize money as determined by the final season standings.
