Police have accused magistrates of allowing a shameless single mother to treat police officers like her "personal punchbag" after she escaped jail for her 11th violent attack on them.

Dawn Walker, 34, has a string of convictions for assaulting police during drunken foul mouthed rampages - including four separate incidents upon officers in this year alone.

But the unemployed former cleaner - who claims employment support allowance - has repeatedly been spared jail after she insisted she was striving to be a "good role model" to her three children.

In the latest incident Walker hurled abuse at PC Thomas Cock, calling him a " fat c***" a " bearded c***" and a " blue-eyed b******" before headbutting him in the face during a night out in Burnley, Lancs.
