Police chased off a naked man throwing rocks at swans at 3am this morning as temperatures in Plymouth dropped to freezing.
Officers were called to a muddy slipway near the China House by residents disturbed by a group of noisy revellers.
Police say a naked man was throwing rocks or stones at swans on the waterfront.
The group moved on when the police arrived, but officers were unable to catch the naked individual.
Police say they were called by residents but they are unable to explain why anyone would strip naked on a muddy beach at 3am in November.
It does not appear the swans were injured.
