Three members of the British National Party, including a Keighley councillor, were arrested at their homes early today by police probing a controversial TV film about their activities.

Steve Barkham and David Midgley were taken from their homes in Eccleshill and Buttershaw. Taxi driver Chris Kirby, the councillor for Worth Valley, was arrested in Keighley.

Police made the arrests following the screening last Thursday of an hour-long documentary showing the activities of the BNP in Bradford.

Police have been minutely examining a tape of the programme to see whether anyone in it broke the law by inciting racial hatred.

A West Yorkshire Police spokesman said: "As part of an ongoing inquiry launched after the broadcast of the BBC Secret Agent programme, police this morning arrested three men. A 23-year-old from Bradford was arrested in connection with racially aggravated public order offences.

"A 35- year-old man from Keighley was arrested in connection with conspiracy to commit damage and a 51-year-old Bradford man was arrested in connection with racially-aggravated harrassment."

The spokesman said the three were being quizzed at police stations in WestYorkshire.
