Police detectives are investigating an apparent assault early New Year's Day on Fairfield Beach Road.

The father of a 20-year-old man called police around noontime to report his son was injured in an incident, which later caused him to have surgical treatment at St. Vincent's Medical Center in Bridgeport for a head injury.

The man told police that his son was assaulted around 3 a.m. on Fairfield Beach Road near Reef Road. He was taken to the hospital by a friend, police said.
