A number of people broke into the building last month following a fire and stayed for three and a half weeks.
Hounslow council had to obtain a court order to evict them and says that they have left the site in a far worse state than they found it.
The building closed in April due to financial pressures from covid and the cost-of-living crisis and caught fire on June the 5th.
The council says there are extensive signs of vandalism with doors kicked in and items stolen.
The authority says their actions have further delayed plans for finding an alternative use for the building to benefit the community.
