A laser engineer who assaulted his partner in front of her children will be sentenced next month.

Derek Joseph, 42, of Lockbridge Way, Milnsbridge , pleaded guilty yesterday at Kirklees Magistrates’ Court to assaulting Rebecca Carter.

Prosecutor Robert Campbell told the bench that an argument had developed over supper between the couple who had been together for a year when they talked about a previous relationship.

He said she had been pushed in the upper chest and that he was shouting at her on the evening of April 20.

Mr Campbell said: “She told him to leave and asked one of the children to call the police.

“He grabbed her by the chin and neck. She told her son to continue calling the police.”

He said she was left dazed by the attack and the children were upset. Broken glass and some liquid were found on the floor.

Mr Campbell said: “The defendant was arrested and said there had been an argument.

“As he was going she punched him. The complainant did suffer some bruising and went to hospital for bruising to the side of her head.

“The complainant is in court and said she does not require a restraining order. No treatment was required at hospital.”

In mitigation, Mohammed Arif, said the couple had been in a relationship for 13 months but there were “issues of trust.”

He added: “There appeared to be some messages on Miss Carter’s mobile phone from another party which drew his concern.

“As a consequence he confronted her. Mr Joseph was hit to the face a number of times by Miss Carter.

“He accepts that he pushed her. He swung a carrier bang at her and caught her on the forehead.

“He is genuinely remorseful and wishes to apologise to her. He regrets his actions.”

Bench chairman, Barry Bedford, said: “She was a vulnerable victim, there were children present. There was no premedidation but you lost it.”

The defendant was granted conditional bail and will be sentenced on September 7.
