A man was rushed to hospital after a council van ran over his head as he lay in a London park.
The man in his 30s was sunbathing in London Fields on Sunday morning when a litter picker in a pickup truck drove over him.
The air ambulance was scrambled and was first on the scene as paramedics rushed by road to aid the injured man. After treatment on the ground, the victim was transferred to an east London hospital where it is reported he received treatment for a fractured cheekbone.
A London Ambulance Service spokeswoman said: "We were called to reports of a road traffic collision on Landsdowne Drive at 10.35am.
"We sent multiple resources including air ambulance, an ambulance and a fast response car, and arrived on the scene in under four minutes.
"We took a patient with head injuries to hospital as a priority."
Police were called to investigate the incident and sealed off the barbecue area of the park.
A Scotland Yard spokesman said: "Police were called by the London Ambulance Service at 10:38hrs on Sunday, 24 July, to reports of an injured man in London Fields, close to Lansdowne Drive, E8.
"At this early stage officers believe that the male was run over by a vehicle as he lay on the ground in the park.
"Officers are not treating the incident as suspicious."
A Hackney Council spokesman said: "This is obviously a serious incident and both the police and ourselves are investigating."
