Raging Pamela Ann Duncan, 33, entered the woman’s home unannounced while she was alone with her children to confront her about the infidelity, before launching the assault whilst her victim was dressed only in a towel.

The 33-year-old mum-of-two then continued to beat the woman in the common close while she was naked until neighbours, who had heard the commotion stepped in to split it up.

Last week Duncan appeared in Dumbarton Sheriff Court after previously admitting her guilt.

Clifford Most, prosecuting, said Duncan lost the plot after finding out her partner had been unfaithful.

She then decided to confront the woman — who she had never met before — about the affair and turned up unannounced at her Tullichewan home at around 8pm on August 22 before letting herself into the property.

Duncan’s surprised victim, who was wearing nothing but a towel, went downstairs to investigate but was soon attacked. After being punched and kicked and having her hair pulled the victim ended up in the common close.

Mr Most said: “The accused continued to assault her kicking and punching her as she was naked and also began to stamp about her body.” Neighbours heard Duncan’s hysterical victim shouting ‘let me go, call the police’ and stepped in to stop the assault.

It was also heard they had to comfort the victim’s five-year-old daughter who saw her mother being attacked.

The two women were eventually separated, Duncan was persuaded to leave and police were called.

Cops then arrived at the scene and saw that clumps of hair had been ripped from the victim’s head. Duncan was later interviewed and told police “Ok I did it, I did it.” Ms Campbell defending said: “Right at the outset she was at pains to stress how remorseful she was of her conduct.” It was heard Duncan had effectively found herself in extraordinary circumstances and been broken after discovering the affair and the child, although she knew it didn’t excuse her reaction.

Ms Campbell added: “Quite simply it seems that matters overcame her and she acted in a manner that can genuinely be said was completely out of character.” Sheriff Colin McKay said Duncan, of Nobleston, Bonhill, had committed a very serious assault He added: “I find it difficult to understand why or how someone in your position could have done this to another woman other than a complete loss of control.” He placed her under supervision for two years and ordered her to carry out 250 hours unpaid work as well as paying £1,000 compensation.
