An anonymous caller tipped police off to a house on Camden Circle that was hosting a noisy "meeting" about 10:40 p.m. Dec. 23.

The caller said 11 people live at the house, and people -- including nine children -- walk around in black robes. 

She said they regularly host meetings and she believes they are involved in some kind of cult.

Police visited the house and found the owner was having a Christmas party. 

There was no excessive noise and the black robes were actually tuxedos, the report said.

There was no indication the caller's other suspicions were valid, it said.
