Material has been seized from a Keighley works premises as part of a police investigation into a major pornography scandal, we can reveal.

Officers removed items - believed to include indecent photographs - from the site, the identity and location of which is not being revealed.

The raid is linked with a police inquiry into the distribution of explicit porn material in Halifax.

Residents on the Furness Drive estate in Illingworth alerted police after youngsters found bags of literature and photographs.

Anxious parents say pornographic material - including graphic letters - have been circulating on the estate for several weeks.

Resident Mrs Sheridan Walton says her daughter is among those targeted. A mobile phone containing obscene messages was sent to the girl.

"We had not ordered the phone. The messages were sick," says Mrs Walton.

Police say a major aim of the investigation at this stage is to determine the age of people shown in some of the pornographic photos.

Inspector Mick Hanks, of Halifax police, told us: "As part of the investigation we have recovered certain material from a Keighley premises.

"We should stress that our inquiries there relate to an individual employee who we suspect could be involved and who may have been storing items.

"There is no suggestion his company is implicated.

"We are still gathering information in a bid to establish if a criminal offence has been committed.

"There is no evidence at this stage that children feature in the material but this clearly is an important line of our inquiries."

Insp Hanks says: "This will be an important factor in deciding if criminal offences, and precisely what offences, have been committed. If people under 16 are pictured this could have a significant bearing."
