A cyclist has been hit by a fire engine responding to an emergency call in south London.
Police and emergency workers cordoned off the junction between Coldharbour Lane and Atlantic Road in Brixton after the incident just before noon on Wednesday.
Paramedics treated the man, thought to be in his 50s, who was seen lying on the road before being lifted him into an ambulance.
He was taken to hospital with a head injury. His condition has not yet been confirmed.
A silver bicycle could be seen leant against the fire engine while an air ambulance circled above.
A man in his 40s, who did not wish to be named, said he saw the cyclist crossing the junction from Atlantic Road before being hit by the fire engine which was travelling down Coldharbour Lane.
He told the PA news agency that fire engines “come so fast up this road”.
“It was a green light and I don’t think he saw it coming,” he added.
Another witness described hearing a “bang” before seeing the man unconscious on the road.
Davood Germi, who gave a similar account, said the cyclist “wasn’t moving” before paramedics took him away.
