Police branded the actions at the public toilets in St.Mary's car park, Much Wenlock as 'unacceptable' and Safety Neighbourhood Team officers have since patrolled the area to ensure there is no repeat.
Police put out a message on the Shropshire Cops Facebook page to say: "Toilet roll was spread all over the interior of the public toilets and the door was jammed.
"Until repairs can be made, this vital community asset is not available and behaviour like this is unacceptable and will not be tolerated. SNT Officers are patrolling the area of the public toilets in St Mary's car park in Much Wenlock following these reports of anti-social behaviour that has affected the availability of the toilets."
The police post added: "If you are affected by anti-social behaviour, please report it to us."
Much Wenlock councillor Dan Thomas said the issue had now been fixed but added: "These actions made a real mess.
"Much Wenlock is a fantastic place with very little anti-social behaviour compared to other areas.
"But when we do get behaviour like this, it is certainly not welcome. I have spoken to the police and they are keeping a close eye on the situation.
"In this instance, they have been very active and we're lucky to have proactive officers here to deal with it."
The incident occurred as events were taking place across Shropshire as part of West Mercia Police's Anti-Social Behaviour Awareness Week.
Chief Inspector Ross Jones said: “Anti-social behaviour is a broad term but has very real, individual and collective victims. It can be things such as graffiti, littering, vandalism, off-road motorcycles, drinking in parks, aggressive and intimidating behaviour and for many people it is one of their biggest concerns in their community.
“It can have a huge impact on our communities and this activity creates an environment where more serious crime can flourish."
