People who repeatedly commit alcohol-related crime will be forced to wear ankle tags that monitor if they are still drinking, under a year-long pilot scheme in London.
The "sobriety tags", to be worn around the clock, will enforce abstinence by measuring a person's perspiration every 30 minutes and testing to see if it contains alcohol.
If any trace is found, an alert will be sent to the offender's probation officer and they can then be recalled to court, where they may be resentenced or face sanctions such as a fine.
The tags register alcohol consumption but do not monitor movement or where people are.(Source: Guardian)
