A security alert on a British Airways plane in Paris was a false alarm, police say.
An airport source said the threat was made about 10 minutes before flight BA303 was due to take off. Bomb disposal experts and sniffer dogs swept the aircraft, while passengers had to pass back through security, the source said.
James Anderson, a 20-year-old entrepreneur, after being deboarded wrote on Twitter, "Everyone onboard had been individually searched by armed officers, while police and fire vehicles surrounded the plane".
'The pilot then said there had been a direct security threat involving our flight specifically'. We will all be led off the aircraft & baggage searched in due course'.
Anderson said passengers were told after about an hour that the aircraft had to move to another part of the airport and that's when security officers surrounded the plane. Now hold luggage being searched by dogs'.
He continued: 'I believe the intention is to return to the same plane assuming the search is all clear.
Anderson posted pictures and video on social media showing passengers evacuating the aircraft with police and fire vehicles nearby.
Anderson told CNN they had not received any further updates from officials but that passengers were re-boarding the aircraft.
'We were told they are also now searching the aircraft with dogs'.
British Airways while regretted for the inconvenience faced by the passengers, they emphasised that security of the passengers is their top priority.
An airport spokesman confirmed the evacuation, saying it was for a "security reason".
'We would never operate a flight unless it is safe to do so'.
The incident follows Friday's terror attack on Parsons Green station in west London.
