'Digi-bike' used to cut crime in Dudley

It is hoped the "Digi-bike" will cut the number of robberies in the town

A four-wheeled contraption has been unveiled as a police force's latest device in the fight against crime.

The "Digi-bike" is being taken out on the streets of Dudley, West Midlands, broadcasting Bluetooth and video messages from its screens.

Its aim is to cut down on street robberies by raising awareness among people carrying valuables.

The 2m (6.5ft) high chariot, with accompanying police officers, will patrol Dudley for the next two weeks.

It will cover Castlegate Leisure Park, Russells Hall Hospital car park, the bus station, the zoo and the Tesco store at Burnt Tree Island.

Det Sgt Mark Rushton said the Digi-bike had been introduced as the number of robberies had risen in the town since April.

"Almost half of all robbery victims since April have been aged 18 years or under, and so we are keen to make those youngsters smarter about keeping their valuables out of sight," he said.
