A case of mistaken identity led to a protective fiancée being sent to jail, after she attacked good Samaritans who assisted her tearful partner.

Amy Louise Rees, 23, of Goshawk Road, Haverfordwest, appeared from custody before Haverfordwest magistrates on Monday.

Rees was due to stand trial for two charges of beating, but pleaded guilty at the start of the hearing.

The court heard that two young women were out in Haverfordwest on January 13, and were near Castle Square when they noticed a woman being shouted at and becoming upset.

Ellie Morgan, prosecuting, said: “They tried to console the girl and see if she needed help or a taxi. The girl was the fiancée of Amy Rees and when she came on to the square she obviously got the wrong end of the stick.”

Rees chased after one woman and grabbed her coat, then turned on the other girl and punched her several times before bouncers intervened.

Miss Morgan said: “One of them was like a haymaker punch.”

She added that the women were left shaken up and anxious by the incident, with bruising and soreness.

She said: “They thought they were offering help to someone who was upset and were assaulted as a result.”

The incident was captured on CCTV footage which was played to the court, and the bench heard that Rees had previous convictions for violence.

Miss Morgan added: “These two girls were trying to be good Samaritans, and that’s what they end up getting for their trouble. It was a frightening experience for them.”

Mike Kelleher, defending, told the court that Rees had already spent six weeks in custody as she had been subject to a curfew at the time of the offence.

He added that the incident had been unpleasant but brief, and there were no significant injuries.

Mr Kelleher told the court that Rees’ partner had called her to say she had been assaulted by two girls, and Rees mistakenly thought that the victims had been involved when she arrived at the scene.

He said: “She found her partner in tears and two girls standing over her. Perhaps an exchange of words would have stopped this, but she was protective and had been drinking.”

Mr Kelleher added: “It was mistaken identity.

"It was a genuine mistake on her part and something that she does apologise for.”

Magistrates sentenced her to 23 weeks in prison and ordered her to pay £620 in costs, £375 compensation to each victim and a £115 surcharge.
