Four people arrested after a protest over alleged tax avoidance by big businesses at Manchester's Arndale shopping centre have been released.
About 30 campaigners stormed the centre on Saturday afternoon, forcing Topshop to roll down its shutters.
Police said the protest became unreasonable and shoppers and workers were being intimidated.
A 38-year-old man held on suspicion of criminal damage has been bailed. Three others were released without charge.
Greater Manchester Police said the protest organisers had previously agreed to go to Cathedral Gardens but not enter the Arndale Centre.
The force said it was committed to supporting "reasonable, peaceful protests" while protecting the community.
The incident happened a week after protesters from the group UK Uncut forced Topshop's store in Oxford Street, London, to temporarily close.
