An investigation has begun after an elderly man was allegedly thrown off a bus service from Norwich to Long Stratton.

A woman lodged a complaint after she reported witnessing the incident on the number 35 First Eastern Counties service on Friday.

She said that the pensioner, who had a shopping trolley with him and had difficulty walking, lost his footing as the bus started to move before he was seated.

The man's trousers started to fall down and the driver demanded that he leave the bus, the woman claimed.

Hugo Forster, general manager for First Eastern Counties, said: 'We have been made aware of the incident and will be undertaking an investigation into the allegations.

'To clarify our policy on the matter of customers being asked to leave the bus.

'We would not under any circumstances, expect any one of our drivers to request a customer to leave the bus, unless there was just cause to do so.

'Our drivers do have a duty of care and consideration to all customers who travel with us at all times, but equally they will not tolerate any incident that may cause embarrassment, inconvenience or annoyance to other customers travelling with us.'
