Police are appealing for witnesses after the victim, who was walking in The Boulevard towards the roundabout at Palatine Road at 5.20pm, was touched as she walked past a man.

He was white, 5’ 8” and of a skinny build with collar length brown hair.
He was in his late 30s or early 40s and was wearing a light beige jacket and trousers.

“The Boulevard is a very busy road and I would like to speak to anyone who may have seen the incident or the man behaving suspiciously in the area. I would also urge anyone else who may have been approached by him to contact us.”
