Bag that screams when snatched

A bag that screams if it is snatched is the latest innovation in the fight against street crime.

If it is violently pulled away from its owner, the shoulder strap detaches and sets off a 138-decibel alarm.

It is on sale at Selfridges from next week for £109.99.

The bag design is part of an initiative between the Metropolitan Police, the Design Council, crime charities such as the Jill Dando Trust and Suzy Lamplugh Trust, and design firm Vexed Generation.

One of the products is a computer laptop bag with a twoway-strap of slash-resistant material and a combination lock.

Other products include a record bag with the same security, a fully-protected rucksack and shoulder bag, a wrist-holder for mobile phones and a body safe-belt which holds a mobile phone, cards and keys.

All are designed to protect the public from criminals but can also be used as everyday fashion accessories.
