SUPPORTERS of the Justice for Christopher Alder campaign are set to hold a meeting later this week as calls for an inquiry into his death go on.

The campaign group will gather at Burnley's Red Triangle Caf, St James's Street on Thursday for a special documentary screening about deaths in custody.

The Burnley sister of former paratrooper Christopher, who died in police custody five years ago, will address the meeting.

Janet Alder and supporters marched on Downing Street last week to demand a public inquiry into Christopher's death after five police officers were cleared of neglect of duty.

Janet presented Prime Minister Tony Blair with a petition signed by hundreds of people calling for justice for her brother.

Christopher, 37, died face down with his trousers around his ankles after he was arrested for a breach of the peace outside a Hull nightclub.

An inquest concluded that he was unlawfully killed. Five police officers, Sergeant John Dunn, 40, and PCs Neil Blakey, 42, Mark Ellerington, 37, Nigel Dawson, 41, and Matthew Barr, 38, were cleared of neglect of duty at an independent hearing following Christopher's death at Queen's Gardens police station, Hull, on April 1, 1998.

In the criminal trial that followed, all five officers were cleared of manslaughter and misconduct in a public office.

Janet and a group of supporters who run the Justice for Christopher Alder Campaign joined a national demonstration involving families of people who have died in police custody.

Janet said she and her supporters were pursuing possible civil action against the officers involved.

The trip was organised by The United Families & Friends Campaign (UFFC) which was set up in 1997 to stop deaths in custody and to ensure full investigations are carried out if someone does die.
