A VIOLENT son brutally attacked his mother - and later threatened to "cut her up" and "dissolve" her in a bath.

Joshua Garroch turned on Angela Law at her home in Paisley, Renfrewshire on March 6 last year.

The 23-year-old initially struck while Angela was on a video call to her sister.

A judge heard how the attacks included Garroch trying to smother his mum.

Garroch is now behind bars after he pleaded guilty to assaulting Angela to her injury and danger of life.

He further admitted breaching bail as well as behaving in a threatening and abusive manner.

Garroch is due to be sentenced next month.

Prosecutor Sheena Fraser told the High Court in Glasgow how a row was sparked over a mobile phone.

Angela went on to video call her sister in Manchester.

Miss Fraser: "During this conversation, Garroch assaulted his mother by grabbing her by the hair and dragging her to the floor.

"He then repeatedly kicked her on the face and body as she screamed at him to stop."

Angela's shocked sister heard the attack and called police in Manchester, who alerted colleagues here.

When officers turned up, however, no complaint was made.

But, later that night, Angela telephoned police while her "angry" son could be heard in the background.

Miss Fraser: "Once the call ended, Garroch again assaulted his mother by taking a pillow and pushing it in her face causing her to struggle to breathe.

"He shouted at her: 'I f*****g hate you'."

Police again arrived and found Angela with a black eye and swollen face. She told how her son was responsible.

Garroch was still in the flat with his behaviour described as "erratic".

After being held, he blurted out: "Wish I had kept stamping on that tramp's head.

"She is lucky she did not get double stomped. F*****g wish I had held a pillow over her head. I will murder her and make her suffer."

He was later granted bail by a sheriff, but in October last year, he flouted the order by returning to his mum's.

On one occasion, Angela said she loved her son, but admitted she was also "scared" of him.

Raging Garroch replied: "You are lucky because next time I am going to put you in the bath, cut you up and dissolve you."

A distressed Angela ran out her house and called police for help.

Garroch was later caught, but insisted he had only been "checking" on his mum.

Geoffrey Forbes, defending, told the court there was a "complex background" between mum and son.

Lady Stacey adjourned the case for reports.
