Protesters gather at Birmingham Bullring centre
Police advised Bullring staff to prevent people entering the centre
About 100 people gathered outside the Bullring shopping centre in Birmingham in an impromptu protest.
The protesters began gathering at about 15:00 BST and a Bullring spokesperson said they had been advised by police to stop people entering the centre.
Police said no crimes have been reported and the motive for the protest "remains unclear at this time".
One person caught up in the protest told the BBC it was over a US-made anti-Islam film, Innocence of Muslims.
Masud Khan said the protest, which he heard about by word of mouth, was "very peaceful" and involved "just chanting".
A BBC reporter at the scene said the protesters had begun to disperse after 18:00 BST.
Police said no crimes have been reported and the motive for the protest "remains unclear at this time".
