DETECTIVES have launched an urgent appeal for information to anyone in the two counties who has returned from Bali in the past week.

Following the devastating bomb that killed up to 200 people in the Indonesian island's Kuta Beach resort on Saturday, police are appealing to anyone who stayed there to come forward with anything at all they feel may be useful.

Police especially want to see photographs and video footage taken in the area before the bomb went off and at the time of the blast.

The powerful car bomb, which contained traces of military-grade explosive, ripped the Sari nightclub apart and turned it into an inferno, killing hundreds and injuring and maiming hundreds more.

Tom Holmes, 39, a former Bromsgrove School pupil, is missing, feared dead and Neil Bowler, 27, a former pupil at The King's School Worcester, was among those killed. In all, more than 30 Britons were killed.

A spokesman for West Mercia Police said the force was making the appeal for information on behalf of the Metropolitan Police's anti-terrorist branch, which is assisting the Indonesian authorities with the investigation.

"Anyone who has returned from Bali in the past few days and thinks they may have seen something suspicious - anything at all - is asked to contact us on the special anti-terrorist hotline," said the spokesman.

"In particular, video footage and photographs taken in the area my be especially helpful to Deputy Asst Commissioner Peter Clarke, who is the national co-ordinator for terrorism."

The spokesman said a team of Metropolitan Police officers had flown to Bali last Sunday to help with the investigation.

"They will be offering support and assistance in the identification of victims, and also helping in the forensic search being carried out.

"They are also supporting and assisting the family and friends of British victims."

No one has claimed responsibility for the bomb, but the finger has been pointed at the al-Qaida terrorist network.

Anyone with any information should phone the anti-terrorist hotline on 0800 789 321.
