Users of popular social media app Snapchat have been warned of a "creepy" update.
It allows people on Snapchat to locate users down to their street address, and even reveals how long it would take to get there.
The "Snap Map" update has sparked privacy and safety concerns among parents and experts.
In March last year, a 16-year-old girl was sexually assaulted in Brighton after gatecrashers using the maps feature tracked down a party.
