Eleven firefighters were injured after two fire engines crashed while on the way to a 999 call near Canary Wharf last night.
One fire fighter was trapped due to the nature of his injuries and rushed to Royal London Hospital at Whitechapel, but was released early this morning.
Ten others were treated for shock and minor injuries and six were taken to hospital.
The fire engines, from Shadwell and Poplar stations, were responding to a 999 call at a store room in Westferry Circus when they crashed.
The collision happened at 7.43pm and a fire rescue unit from Millwall, Homerton and Bethnal Green fire stations attended the scene.
The store room fire was dealt with by firefighters from Bethnal Green, Dowgate, Plaistow and East Greenwich, with the blaze under control by 8pm.
An investigation into the collision will now take place.
