Police are searching for a man who broke into a Massachusetts church, donned the priest's robes and committed a lewd act at the altar.

Surveillance footage released by Cambridge police shows the identified man inside St. Sava Serbian Church after he entered through an unlocked door around 3:15 a.m. on September 29.

Police say he put on priest's clothing and then walked around the empty church for about 45 minutes before stripping down and performing "a lewd, sexual act on the altar of the church."

The incident was discovered when the church's priest, Alexander Vlajkovic, reviewed surveillance video. Church members say the man also left behind a mess of soda and wine.

"There's a strong sense of violation throughout the community," Church Board President Alexander Pogorzelski told Fox25. "We had to perform a consecration before we could perform another liturgy because of the desecration."

The church is now keeping its doors locked between services.
