Millwall beat Leeds 2-0 last weekend in the Championship, and after the match got underway at the New Den rival fans faced-off at London Bridge train station.
There was a heavy police presence at the station in order to contain the charged atmosphere as fans from the two clubs met, and amid the mayhem one fan filmed a mad moment when a police dog got a little bit confused.
Rather than looking to contain the fans, the police dog set about attacking one of the policemen by biting him in the arse.
Watch the fan footage below.
