Detectives in Derry/Londonderry are investigating a sexually motivated attack on a woman in her 40s in the Waterside area on Saturday 2 November.

The woman was walking her dog in Top of the Hill Park shortly before 3pm when she was approached by a man armed with a kitchen knife. The man grabbed at the woman but she called out and swung her dog lead at him, prompting him to run off.

Police responded quickly to the area and conducted a thorough search however the attacker had left the area.

It’s believed the suspect headed in the direction of Corrody Road. He is described as a white man in his 20s, around 5’ 11” tall with a slim build and was wearing all black clothing. He had his hoody pulled tight around his face.

Detectives are investigating the possibility that this attack is linked to a similar attack in Drumahoe on Friday night.

Detective Inspector Ross Olphert said: “We understand that there will be concern in the community at a second knifepoint attack on a woman in just two days, with this latest one occurring during daylight hours, however I can assure residents that a focused, tactical patrolling plan - which includes a high visibility police presence in key areas such as our local parks - has been implemented and there will be an increased police presence across the city in coming days.

Whilst we are carrying out a number of enquiries to establish if there is any definitive link between these two attacks, I can assure residents that there is no link to attacks in the city centre last week. In both of those cases a suspect has been identified and those cases are ongoing.

We are engaging with our communities and partners in the city around what we can do, as a collective, to ensure women and girls feel safe and empowered to go about their lives without fear.

In the interim I would ask that if you notice someone acting suspiciously or if a person’s behaviour causes you concern, do not approach and instead call police immediately.
