"Officers are continuing to patrol the local area and if anyone would like advice, please do speak to them or contact them in the Neighbourhood Office, all contact details can be found on our website.

"We’d also like to offer the following common sense safety advice:

• If you’re heading our walking or running, let someone know where you're going and for how long you’re planning to be out.

• Consider downloading a fitness tracker app on which a trusted family member or friend can trace your movements, just remember to lock your privacy setting from public to private.

• Take your phone out with you and make sure you have your battery charged.

• Plan your route beforehand, taking into account whether it will be a busy or well-lit area.

• Consider running or walking with others if possible.

• If you feel uncomfortable, or at risk, look for a place of safety, such as a shop or anywhere where there are other people and tell someone your concerns.

• Be aware of your surroundings - concentrate on what and who is around you.

• Don’t be distracted by using mobile gadgets and MP3 players. If you are listening to music, if possible use just one headphone so that you are aware of someone approaching you.

"Once again, thank you for your support and if anyone has further information about this incident, please call 101 quoting log 580 3/9/18."
