A BA passenger plane flying near Heathrow Aiport was not struck by a drone as first suspected , the government has ruled.

Transport Secretary Patrick McLoughlin told MPs the collision was no longer being treated as a "drone incident".

However, air accident investigators said they are not ruling out the possibility - although no evidence to suggest it was a drone has been found as yet.

Police officers at the time believed it to be a drone, but now Mr McLoughlin said "there is nothing to look at" in the investigation.

An investigation was launched by the Metropolitan police and air accident investigators into the April 17 incident after the plane, flying from Geneva, was struck by an object .

The Airbus A320 was carrying 132 passengers and five crew as it approached the airport and landed safely.

Anyone caught flying an unmanned aircraft above 400ft or beyond their eyeline can be convicted under the Air Navigation Order 2009, with a maximum sentence of six months' imprisonment.
