Murder squad detectives continue to question a 31-year-old man over the bloodshed with nine victims still being treated in hospital. Two of the injured adults were in a critical condition and five children were also receiving treatment after the mayhem on Friday afternoon in the Welsh capital. South Wales Police were last night granted a further 36 hours to detain and question the arrested man. Detective Superintendent Paul Hurley said the suspect carried a weapon and left his Iveco van to physically assault people. Police want to identify and recover the weapon, which was believed to be a crook lock. There were also unconfirmed reports that police were investigating if the driver was involved in a domestic incident before the rampage. Witnesses were urged to get in touch and asked for information about a mystery black Renault Clio, on a 05 registration plate, seen driving on the wrong side of the road of Western Avenue, not far from Cowbridge Road West. Police said a key part of the inquiry was focused on establishing who owns the white van. The first incident to be reported was in Crossways Road in Ely at 3.30pm. This was soon followed by other reports of hit-and-run collisions in several locations in the west of the city, including Grand Avenue, Cowbridge Road West and the Leckwith Retail Park. A special church service will be held later today in Ely, Cardiff, in support of the victims and their families.
