POLICE are warning members of the public after potentially dangerous medication was lost.

A grey handbag was misplaced, containing potassium supplements, fentanyl lozengers, orimorph (morphine), levomepromazine, cyclizine and dexasone.

It is believed that the bag may have been lost yesterday, Thursday, March 5 in or around James Cook University Hospital or in or around the Parkway Centre in Coulby Newham.

If the medication is taken by someone that they are not prescribed to, it could prove very dangerous.

Officers would ask anyone who may find the bag to hand it in to their nearest pharmacy or police station.
