The police have also asked parents and guardians to share the following message with their children: “Make sure that you know where children are going and for how long they are planning to be out. If they are with friends, do you have their parent’s numbers?
“Remind them not to walk alone and stay in a group. Stick to busy or well-lit areas.
“Ensure that they take their phone out with them. It should have a fully charged battery.
“Tell them to ask for help if they need it. If they 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 their concerns. If they feel in immediate danger, shout for help – draw attention to themselves.
“Remind them to be aware of their surroundings – concentrate on what and who is around them and don’t get distracted by their mobile phone.
“Report anything suspicious to the police; 999 in an emergency and 101 for non-emergencies.”
