Police also carried out a controlled explosion nearby following reports of a suspect device that later turned out to be a bag of clothes.
The explosion is said to have gone off just outside the entrance to the venue as thousands of people were leaving.
If confirmed as a terrorist attack it would the worst atrocity in the UK since 56 people were killed in the 7/7 London bombings in 2005.
