A 23-year-old man has been arrested after an ambulance crew was attacked on board their vehicle by a group of youths in Cardiff.

A paramedic suffered a broken rib and facial cuts as he and a technician answered a late night emergency call in the Grangetown area on Saturday.
The ambulance service said a group of youths boarded the vehicle at around 2350 GMT and attacked the men. The technician was treated for shock.
