Ankle tags to monitor offenders' alcohol consumption

31 July 2014 Last updated at 15:33 BST

Repeat offenders convicted of alcohol-related crimes will be forced to wear ankle tags that monitor their drinking, under a new pilot scheme.

The mandatory tags record levels of alcohol in the sweat every 30 minutes.

The 12-month trial in four London boroughs gives courts the ability to ban people from drinking alcohol.
