Four people suspected of staging car accidents in a "crash for cash" scam, have been released as police continue their investigation.

The three men and a woman, aged between 30 and 53 and all from Keighley, were given police bail pending further inquiries.

They were arrested in dawn raids on homes in and around Keighley town centre yesterday.

Officers seized a large number of financial documents and a high-value motor vehicle.

Detectives had worked with investigators from the Insurance Fraud Bureau for three months before the swoops took place.
