Rap star Dizzee Rascal was hauled off a plane at Heathrow Airport in London on Saturday for allegedly hurling abuse at a stewardess — and now he could face a life ban from British Airways. The singer, whose single Bonkers was a No 1 hit, was escorted off the flight at Terminal 3 by police called in to attend the disturbance. The East London-born singer is said to have hurled foul-mouthed insults at the stewardess as he sat in First Class. He had been on his way to Portugal to the Optimus Alive! festival, where Coldplay and Foo Fighters were also on the bill, but as a result of the incident was unable to play there. Tempers flared on the Airbus 320 as it sat waiting on the tarmac for more than an hour because of technical problems. Rascal — real name Dylan Kwabena Mills — was sitting with a friend and band members when he is alleged to have made the outburst. Officers arrived after the crew radioed through to police. The star was taken off flight 506 to Lisbon at 11.20am, along with another member of his entourage.

Then he threw a tantrum with staff, and passengers were told something was wrong. \"After the incident his band members were still on the flight. They started kicking off, too, shouting that they couldn\'t play without him because he\'d been thrown off.\" An airport source said: \"The singer was verbally abusive to staff. This will not be tolerated. He was taken off the aircraft and was not allowed to continue his route on any other British Airways plane. There will be an internal investigation and a decision will be taken as to whether he will ever be allowed to fly with British Airways again.\"
