A teenager in the UK has been injured after having an 'unknown substance' sprayed in his face.

The attack happened outside a pizza restaurant in Bristol at around 8:45pm on Saturday night.

According to police, a 16-year-old boy was sprayed with the substance after a dispute with another male.

The boy was taken to hospital with injuries described as "potentially life-changing but not life-threatening".

Detective Inspector Richard Marsh said: “This is a very concerning incident in which a bottle containing an unknown substance, possibly a type of corrosive, has been sprayed into the face of a teenage boy.

“The victim is being looked after in hospital by medical experts but has some serious injuries which may be permanent."

He added that the bottle used in the attack hasn't been found, urging anyone who finds a bottle with liquid in the area to not pick it up.
