STOCKTON SPRINGS (AP) — Police are investigating after someone spray-painted swastikas on a Stockton Springs church, and the pastor says the church was targeted because of his opposition to same-sex marriage.

The blue swastikas were discovered Tuesday on the front door of Stockton Springs Community Church and on two outside signs.

Maine voters on Tuesday approved a referendum legalizing gay marriage.

Protect Marriage Maine, which opposes gay marriage, issued a statement on behalf of pastor Steve DeGroft saying the vandalism was an attempt to "silence and intimidate" the church's opposition to same-sex marriage.

David Farmer, spokesman for Mainers United for Marriage, said the pro-gay marriage group deplores any act of violence and find the symbols offensive, but says there's no evidence he knows of to suggest the vandalism was related to the referendum.
