The East of England Air Ambulance was scrambled to Bedford after a cyclist was in collision with a rush-hour bus.
The incident happened in Caudwell Street, which was closed for two hours on Tuesday (October 6) morning to allow the emergency services to attend.
The helicopter landed near Britannia House, Palgrave Road, where an eyewitness saw three paramedics jump out and race towards the town centre.
An East of England Ambulance Service NHS Trust spokesmand said it received a call at 8.56am and dispatched two ambulance officers, an ambulance crew, a rapid response car and the East Anglian Air Ambulance.
“The air ambulance landed close to the scene where a man in his late 20s had suffered head injuries.
“It was not required to fly him to hospital as he was in a stable condition and transferred by land ambulance to Bedford Hospital South Wing.”
The incident involved a Stagecoach bus on the 42 route between Bedford and Flitwick.
Stagecoach East managing director Andy Campbell said: “We are working with the police to try to identify what happened as there was conflicting witness reports over whether the man was riding the bike, or he was pushing it and crossed infront of the bus.
“The bus was travelling relatively slowly as it was coming round a bend at that point.
“We will provide the police with the CCTV footage to find out what happened.”
He added: “I hope the gentleman is recovering well.”
A Bedfordshire Police spokesman said officers were called to the scene shortly after 9am, when the road was closed.
It was reopened by 11am.
