An 18-year-old student is in hospital with serious head injuries after being hit by a bus on a university campus.
Police said the incident happened at the University of Sussex in Falmer, Brighton at about midnight on Saturday.
The pedestrian was taken to the Royal Sussex County Hospital and then transferred to Hurstwood Park Neurological Centre in Haywards Heath.
A spokeswoman for the university confirmed the crash happened on campus and the man was a student.
She said: "We can confirm that one of our students was struck by a bus on Refectory Road on campus in the early hours of Saturday morning. He was immediately taken to hospital and his family were contacted by the police.
"Our thoughts are with him and with family and friends, and we wish him a safe recovery."
"This was an unusual incident, as campus roads are generally very safe."
She said Friday was the last day of term and most of the students who lived on campus had now left for the Christmas break.
Roger French, managing director of Brighton and Hove Bus and Coach Company which operates the bus, said police obtained CCTV of the incident after the crash on Saturday.
He said: "Our heart goes out to the student."
Sussex Police want to speak to anyone who was on the bus or any witnesses who saw the crash in Refectory Road.
