Police attended as squatters were moved on from a former Co-operative shop in the city centre.
The group occupied a disused site in St Augustine's Parade which until recently housed a Co-op.
They stayed for around a week and a half, before being evicted on March 1, said an employee of a business in the area.
Choosing to remain anonymous, he said: "We noticed something odd was going on because five people, probably more, were going in and out of there every hour.

"Then a day or two before they left, they broke the fire alarm system for all the businesses in St Augustine's Parade."
The worker added that the words 'Hedge Monkey' were graffitied on the site's window-front during the squatters' stay.
Hedge Monkey is both the name of a Somerset ale and a term for someone who wears "psychedelic tie-dye clothes of natural materials", according to Urban Dictionary.
An Avon and Somerset Constabulary spokesperson said: "The neighbourhood team was made aware that squatters had moved into a property in St Augustine’s Parade on Wednesday, February 27.
