It's the latest in a string of incidents of vandalism at the building
Public toilets in Castletown Town Hall will be closed until lunchtime due to damage.
The local authority is asking parents if they recognise bicycles left at the building to contact them on 825005 to discuss the ongoing antisocial behaviour.
It's said repairs will be carried out during the day but alternative facilities are available on the quayside.
The commissioners say an accessible toilet in the disabled parking area remains open to anyone who may need to use it, a radar key is not required.
