AN investigation has been launched by the BBC after one of its regional presenters swore on air.

Stewart White, of BBC Look East, was presenting the headline of the programme's lead evening news item when the incident took place.

Mr White was speaking from Soham, Cambs, where a search is taking place for missing ten-year-old girls Holly Wells and Jessica Chapman.

In the piece, which appeared to be pre-recorded, he started to speak then made a mistake and then swore.

A spokesman for Norwich-based Look East said the matter was being investigated and a "handful" of complaints had been received from viewers.

Last month Mr White apologised at the end of a news item after a male voice was heard to utter a series of expletives during the Look East lunchtime news.

The BBC apologised and said there had been a technical fault.

Mr White was in a studio in Norwich carrying out an interview with a Cambridgeshire County Council youth worker about the rise in the use of crack cocaine in Cambridge when the outburst was broadcast. The expletives included the phase, "for ***** sake, get that sorted out".
