The sound of the police helicopter flying overhead could be heard by many across Swansea on Saturday night.
The National Police Air Service were circling over the Manselton and Brynhyfryd areas in particular as they followed a motorcyclist who had made off from South Wales Police officers.
The vehicle was later tracked down, but had been abandoned.
The force is now continuing their investigations.
