Just before midnight on Sunday evening, Ayer police received word of a single vehicle auto accident on Washington Street near the former Ayer fire headquarters. The car crash involved a 25-year-old man from Groton.
The driver, who was not wearing his seat belt, reportedly hit a telephone pole. He was found unconscious in his blue 2008 Mustang with what an Ayer police lieutenant described as “obvious head injury.” The Ayer Fire Department took him to Nashoba Valley Medical Center. He was later transported to Beth Israel Medical Center in Boston and was listed in critical condition as of Monday afternoon.
Authorities say they are still investigating the cause of the motor vehicle accident.
