A young woman has ridden into Tesco on a horse.
Filmed by laughing friends, the woman, named as Indiana Ralph, 21, trotted into the store, believed to be in Bishops Auckland, County Durham, and drank a can of Pepsi.
The stunt appears to be related to the 'NekNomination' challenge, where people perform dares while drunk.
As a security guard tries to remonstrate with her, the woman reads out a list of people nominated to carry out the next dare, saying: "Don't let me down".
The NekNomination craze has been branded irresponsible for encouraging dangerous behaviour.
In Northern Ireland, there have been calls for a ban after the death of a teenage boy.
