Long Lane in Hillingdon is closed in both directions after a car crash.

London Ambulance Service (LAS), London Fire Brigade (LFB) and Hillingdon Police are at the scene of the collision, which is said to have happened within the last hour.

According to LAS officer Chris Hawkswell writing on Twitter, the collision involves three cars, one of which is overturned.

Six patients are being assessed by LAS officers. One person is believed to be trapped inside a vehicle.

Earlier this morning, Police, LAS and LFB attended an incident which saw the A40 close in both directions in Hillingdon, causing major tailbacks in both directions as far as Ruislip and Denham.
