A THUG who thumped a fellow inmate in an unprovoked attack within Greenock Prison has been given a further sentence.

Sarah Latimer took her unwitting victim from behind by striking her head and pulling her hair in the jail's Darroch Hall.

The violent 36-year-old was serving a sentence for assault at the time.

Latimer said afterwards: "She's always in my face."

Greenock Sheriff Court heard how the thug and the other woman had to be pulled apart by guards as they tussled on the floor.

Prosecutor Lindy Scaife said: "The complainer walked into the hall, the accused was at the entrance and in an unprovoked attack she approached her from the rear and struck her to the back of the head.

"She grabbed her hair and pulled it and a struggle ensued."

The incident happened at around 4.45pm on October 22, 2017.

Latimer's lawyer asked for her to be spared a fresh jail term, urging a 'structured deferred sentence'.

The solicitor said: "There is a difficult balance to be struck with someone who has a concerning history of offences, but she is also classed as a vulnerable individual."

But Sheriff Andrew McIntyre responded: "The background report says that she has been offered a high level of support but engages in a superficial manner.

"She describes the victim as always being in her face."

Sheriff McIntyre told Latimer: "You were serving a sentence for assault and you have a conviction for threatening and abusive behaviour involving a knife.

"While you were serving your sentence you assaulted another prisoner unprovoked.

"It is important that people in prison are not subjected to violence.

"This is particularly serious given your record.

"It would be quite wrong to mark this in any way other than prison."

Latimer, whose address was not given in court, was sentenced to ten months.
