British boxer Billy Joe Saunders has been caught on film launching a foul-mouthed tirade at cops - telling one to: 'F*** your mother!'

The two-time world champion flew into a rage when police caught him and three others illegally hare coursing.

Saunders, 36, who famously beat Chris Eubank Jr in 2014, was due for a spectacular comeback this year after a four-year break from the sport.

In May this year the fighter had met with boxing promoter Frank Warren to discuss returning to the ring as a super middleweight.

But this week Saunders and three other men were sentenced for illegally using dogs to chase and kill hares in Lincolnshire.
