A man “mocked and degraded” his partner as he repeatedly punched her in the face in a drunken attack.
Scott Lambert was locked up for five months over the “ferocious” violence used against the woman in her own home.
Lambert, 34, carried out the attack on the same day his grandfather had died in his arms.
Leeds Crown Court heard Lambert argued with his partner after they had been drinking at his home in Middleton on December 27 last year.
Lambert left the property to go to her own home nearby after he became abusive. The defendant also went to the property where he carried out the attack.
The woman fell to the ground and Lambert “straddled” her before punching her repeatedly to the face.
Lambert continued to humiliate the woman by mimicking her pleas for him to stop the attack.
The attack ended when she managed to escape the property. She suffered bruising and swelling to her eyes and nose.
Lambert, of Middleton Park Grove, Middleton, denied the attack but was found guilty of common assault after a trial.
Antony Farrell, mitigating, said Lambert’s grandfather had died in the defendant’s arms earlier on the day of the attack.
He said Lambert was upset because he had been very close to him. Mr Farrell said Lambert was sorry for what he had done and had not drunk alcohol since the incident.
Recorder John Thackray told Lambert he was fortunate that he had only been prosecuted for common assault rather than assault occasioning actual bodily harm as he would be facing a longer sentence. He said: “The offence for which you fall to be sentenced was a sustained and ferocious attack.
“Only an immediate custodial sentence can be justified.”
