A hi-tech bracelet could soon be helping civil rights and aid workers at risk of being kidnapped or killed.
When triggered, the personal alarm uses phone and sat-nav technology to warn that its wearer is in danger.
Warnings are sent in the form of messages to Facebook and Twitter to rally support and ensure people do not disappear without trace.
The first bracelets are being given out this week and funding is being sought to make many more.
The bracelets have been developed by the Civil Rights Defenders campaign group in a bid to help workers in war zones and other areas of conflict.
The chunky bracelet has mobile phone technology buried within it that can send prepared messages when the gadget is triggered.
Alerts can be sent manually by a rights worker if they feel under threat or are triggered automatically if the bracelet is forcefully removed. The alarm sends out information about its owner and where they were when they were attacked. Other staff nearby will also be alerted so they can start to take action to help anyone in distress.
