A fashion accessory designed to deter violent attacks on women is on sale in Lincoln.
The PFO One bracelet, which retails at £179, sends an alarm message to three nominated people if it is pulled from the wearer's wrist. When activated, the three specified people will have the wearer's location sent to their mobile phone.
John Greed Jewellery, in High Street, has eight of the hi-tech bracelets in stock.
Nathan Roat, assistant manager at John Greed Jewellery, said: "The fact that the safety aspect has been combined with a piece of jewellery is something we expect to appeal to people."
The bracelets, which have been designed in Sweden, require a monthly subscription and have been developed in conjunction with G4S.
Rosie Kelly, 20, a second-year student at the University of Lincoln, said: "I like the idea of it but I'm not sure I'd wear it because it looks quite chunky and not that versatile.
"I probably wouldn't spend £179 on it either since there are similar phone apps that are cheap or free."
Detective Inspector Sean Baxter from Lincolnshire Police's public protection unit, said: "It is really important that people don't rely on devices like this too much as they do have limitations and they shouldn't replace common sense and taking sensible precautions."
