Sarnia police are looking for those responsible for a couple of acts of vandalism at London Road Public School.
Police said someone tagged the school with white spray paint sometime between Thursday and Friday evening.
They said the theme appears to be the letters "PK" along with several vulgar words.
Earlier Monday morning, officials found what appeared to be dog feces thrown against doors and windows.
Police said this sort of crime costs time, and money, and is a major eyesore for the neighbourhood.
Anyone with information is asked to call Sarnia police or Crime Stoppers.
