Police are looking for a St John medical bag that disappeared from an ambulance while staff treated a seriously injured teenager.
St John staff were called to Cross St, Papakura, yesterday about 8pm to treat a 13-year-old boy who fell off a bicycle.
The scene was very volatile, and a number of people were heavily intoxicated, said prevention manager Acting Inspector Matt Hoyes.
The patient and others at the address were reportedly aggressive to ambulance staff.
Ambulance staff left quickly taking the patient to hospital, but did not realise a medical supplies bag was missing.
