Panes in one of Sulby Methodist Church's stained glass windows have been smashed at some point over the last week.
Police are investigating the damage, and believe it happened some time between last Sunday, and Friday.
They think it may have been caused by a football being kicked against the window.
Officers want to speak to anyone who may have noticed people in the church grounds between the aforementioned dates.
If you have any information call Ramsey police station on 812234.
