35-year-old Jamie Willis attacked another man outside the Blue Moon Pub in December 2023.
He'd asked the victim if he wanted to smoke cannabis and then punched him in the head causing him to fall to the ground.
Willis stamped on his back and kicked him before he went through the victim’s coat pockets and stole £45 in cash, a Samsung mobile phone and a bottle of Hugo Boss aftershave.
The victim got up and tried to confront Willis who then hit and punched him in the head again.
After this, the victim left in the direction of East Road and Willis also left the area.
Two months previously on Sunday 1 October, Willis attacked his former partner in Sturton Street at about 10:30pm.
She suffered minor injuries and Willis was arrested on Wednesday 4 October in Warkworth Terrace and released on bail.
On Friday 2 August, Willis, of Brooks Road in Cambridge was jailed for eight years and two months having been found guilty of robbery at an earlier hearing.
He also plead guilty to actual bodily harm at an earlier hearing.
Willis was handed an indefinite restraining order against his former partner and ordered to pay a £228 victim surcharge.
DC Jasmine Rouse:
"Willis is a violent man who is a danger to the public having disgracefully robbed a man and assaulted his former partner in little more than two months.
I am delighted he is now behind bars where hopefully he can reflect on his dangerous and shocking behaviour.
We will tolerate these levels of violence on the streets of Cambridgeshire".
