Police were called to the Bristol depot of a national windows company after a disgruntled sub-contractor blocked the entrance in a dispute over late payments.
One man was arrested by police after an allegation of assault was made and police confirmed they were called to the depot of Anglian Home Improvements twice in the same morning last week.
The arrested man, one of those protesting about not being paid for completed work, was later released under investigation pending further inquiries by police.
