I am a security officer for a private estate. I frequently deal with cars parking in a way that obstructs other vehicles.
On a recent occasion I asked the various tenants of the estate and each denied that the problem card belonged to any of their visitors. I put notices on a couple of the cars with brown tape requesting that the owners move the cars. The notices said that the police would be called and the cars towed if the request was not complied with.
The owner of one of the cars is now threatening to sue me for criminal damage. The tape left only a small amount of residue that can easily be removed with soap and water. Is there any liability associated with my actions?
