Former tennis player Andrew Castle is reported to be in a hostile dispute with neighbours. According to coverage from the Daily Mail and Mail Online, tensions between Castle and surrounding residents have escalated to the point where Castle allegedly reports the neighbours to authorities. The dispute centers on claims that the neighbours built a swimming pool without the required permission. Both outlets frame the situation as a “grudge match” or ongoing quarrel between Castle and those nearby, describing the conflict as deeply strained rather than a minor disagreement. The reports do not provide additional details about the outcome of any complaint or whether the pool was ultimately found to be in breach of local regulations. The information presented focuses on the existence of the deteriorating relationship and the specific allegation regarding the swimming pool, with no further substantiated context included in the shared excerpts.
