An 80-year-old Catholic church in the Diocese of Santa Rosa was struck by vandalism over four days, causing $50,000 worth in damages, reported KCBS.

Nine-inch holes were smashed in five windows of St. Vincent de Paul Church and an unlit Molotov cocktail was thrown into the church library Monday. Police say nothing has been stolen, though the church was broken into on Friday, Saturday and Sunday nights.

Police have no leads in the investigation. They say vandalism has been on the rise in the downtown area. Church officials are considering installing motion detector lights and cameras outside.

Fr. Gary Lombardi told KCBS that minor incidents had begun two weeks earlier.

Graffiti was found in the church plaza. The chalk writings said: “what if you're wrong”, “maybe you're wrong” and “satan loves you,” Fr. Lombardi told KCBS.
