South Wales Police inspector Karl Roberts said: “Those visiting or working at the shopping park have the right do so without feeling intimidated or harassed, and I would appeal to those frequenting the area to meet with friends to be considerate of others and be mindful that if their conduct is deemed to be antisocial or criminal, they can expect to be dealt with appropriately by my officers.
“Our neighbourhood policing teams regularly patrol the area, and anyone with information or concerns is encouraged to stop and discuss with them. Alternatively please call 101.”
