Television and radio broadcasts were interrupted last night to deliver a special alert amid fears a nine-year-old boy was abducted by a middle-aged man driving a car.

Media organisations were alerted soon after the child snatch as part of a national scheme launched last year.

It is one of the first times the newly launched Child Rescue Alert system has been used.

The boy was last seen getting into a red Vauxhall Astra-sized car in Tredington Close in the Woodrow area of Redditch, Worcestershire, at around 7.15pm along with a man aged between 45 and 50.

Based on the Amber Alert system in place in the US, which has helped in the recovery of 311 children in 11 years, the system involves radio and television stations broadcasting messages every 15 minutes for four hours.

When it was rolled out across the UK earlier this year, police said in order to ensure the system is not over-used it would only be engaged in exceptional circumstances.

West Mercia Police appealed last night for any information regarding the boy who is white, about 4ft tall, with cropped brown hair and dark eyes, possibly brown.

Detectives in Portugal were criticised in the wake of Madeleine McCann's disappearance last month for not employing the child rescue alert system.
