Drugs stolen from Huddersfield Royal Infirmary
Vials containing potentially lethal drugs have been stolen from a West Yorkshire hospital.
A total of 46 vials were taken from Huddersfield Royal Infirmary at about 08:00 GMT on Monday, police said.
The missing drugs were 16 vials of Fentanyl, 10 of Pethidine and 20 of Midazolam, all taken from the hospital's endoscopy theatre.
Det Sgt Paul Simm, from West Yorkshire Police, said the opiates "could be fatal if misused".
Fentanyl and Pethidine can, if misused, cause heart and breathing problems. Midazolam acts as a sedative and can also cause breathing problems and chest pains.
Det Sgt Simm said anyone with information about the theft of the drugs, which were clearly labelled, should contact police as soon as possible.
"I am also warning anyone who is either offered any of these drugs, or sees them discarded anywhere, to call us," he said.
