A Middlesbrough fan has been arrested for allegedly urinating in the opposition team goalkeeper's water bottle, police said.
The supporter was facing a ban from watching his team following the incident at Queens Park Rangers' Loftus Road ground during Boro's 3-0 away win.
Video shared on social media showed a man throw a water bottle onto the pitch behind the QPR goal.
Fans talking about the incident on a forum indicated the bottle may have been taken earlier by a pitch invader.

Last month, a Sunderland fan was ejected from the Stadium of Light after he was reported to have defecated on his seat -- although police later said he was merely drunk.
