At weddings and funerals out in the world, he released doves, a universal symbol of peace and love. At home, the police say, he kept something quite different under lock and key: an arsenal of guns and Nazi propaganda.

The police in Laguna Beach, Calif., say they made the discovery at the home of Mitchell Todd, 51, who was arrested on suspicion of making a criminal threat after officers received a complaint that he had threatened a man who hired him to release doves at the funeral for the man’s son.

When the police arrived at Mr. Todd’s home in Huntington Beach, they discovered a cache of more than 50 firearms as well as Nazi propaganda and several pounds of ammunition, according to the authorities.

It was not clear whether Mr. Todd had been formally charged. The police did not return calls seeking comment. Fox 11 reported that he was to be taken to the Santa Ana Jail on Wednesday.
