Chief Inspector Phil Lamb said: “We understand the level of impact this kind of incident can have on communities and we want to make sure that those who are concerned come and talk to us.
“We are present and visible in the Riverside area and we hope this provides an opportunity for people to come up and speak to us, or provide information for the investigation team.
“Our personal safety advice remains the same, try to avoid walking anywhere on your own at night. Get a lift or walk with a friend and stick to busy well-lit areas. Stay alert, don’t be tempted to look down at your phone or plug in your head-phones. Remain vigilant and encourage friends and family to do the same.
“Detectives would like to hear from anyone who saw anything or anyone suspicious on Sunday night between 11pm and 11.50pm to contact us via 101, or just come and speak to us.
“Report anyone suspicious to 101 or 999 if an emergency.
