This is the sickening moment a British tourist was kicked in the head by a group of teenagers in a violent street robbery in Portugal.
Footage of the assault, filmed by the attackers themselves, shows the 18-year-old lying bloodied and unresponsive as members of the group kick him in the head before fleeing the scene in the resort town of Albufeira.
The group is said to have stolen the victim's phone, worth around 600€.
The brutal attack took place in the early hours of July 17 and quickly spread across social media.
But it was separate CCTV footage that ultimately helped police track down the suspects.
