Reports from the scene suggest the man was acting suspiciously near one of the entrances.

He was filming but refused to tell police what or why he had a camera out and as a result, he was detained.

It comes less than three weeks after Salman Abedi blew himself up at Manchester Arena, killing 22 people and injuring at least 119 more.

That attack occurred as thousands of people, including children, piled out of the venue having watched Ariana Grande.

Two weeks later Khuram Butt, Rachid Redouane and Youssef Zaghba went on a rampage on London Bridge, mowing people down and butchering people in the capital's streets.

Eight people were killed and 50 were injured.

Paisley town centre in Scotland was also cordoned off as police sent in the bomb squad.
