Parents are being warned about a 'choking game' craze on social media after a schoolboy lost consciousness and bit through his tongue.
The warning was issued after an incident in Chorley, near Bolton, however police say there have been reports nationally of serious injuries. Families across the UK are being urged to be aware of this craze and to look out for signs their children may be getting involved.
Lancashire Police says officers were called out to a school in Chorley after a number of youngsters took part in the "tap out" challenge on July 5. The craze involves a person putting their arm around the neck of another and applying pressure until they "tap out", indicating that the game should stop.
