Cardiff City fans trashed the toilets in the away end of Ashton Gate Stadium after their team's defeat to the Robins today.
Photos being shared on social media show both the male and female toilets in a sorry state, with the roof panels torn down and debris everywhere.
A spokesperson for Bristol City has confirmed that the damage was caused by some Cardiff City fans in the Atyeo Stand - and that the Welsh club has already offered to cover the cost of the damage.
