HAMPSHIRE police officers are helping with the investigation into a fatal air crash that killed at least 11 people.

Up to 20 people may have died after the Hawker Hunter jet crashed into traffic on the A27 during a demonstration in West Sussex on Saturday (Aug 22).

The vintage 1950s-era aircraft plunged into the road while its pilot attempted a loop manoeuvre as part of the Shoreham Air Show.

Police originally said eleven people are thought to have died as a result of the crash, but have warned that the death toll may rise to 20 once wreckage has been cleared.

A spokesman for Sussex Police said officers from Hampshire were helping them with the recovery of victims from the crash scene and their identification.

Teams from Kent and Surrey constabularies are also helping with the investigation.

The pilot of the plane, Andrew Hill, was among those injured and is now fighting for his life after being put into a medically-induced coma.

Three people - Worthing United footballers Matthew Grimstone and Jacob Schilt, both 23, and 24 year-old personal trainer Matt Jones - were among those killed in the crash.

Motorcyclist Mark Trussler, from Worthing, is missing, while fears have also been raised over Daniele Polito, a father from Worthing who was travelling in the same car as Mr Jones when the plane crashed.

The driver of a Daimler wedding car, who was on his way to pick up a bride for her wedding service but has not been named, is also believed to be among those killed.

The plane's remains may be taken to the Air Accidents Investigation Branch's facility in Farnborough, Hampshire, for examination.

The crash has sparked calls for safety precautions at public air shows to be tightened and the Civil Aviation Authority has said flying displays by vintage jets will be "significantly restricted until further notice" following the disaster.

The organisation has ruled that vintage jet displays will be limited to flypasts while acrobatic stunts will be banned while the investigation takes place.
