A teenager has had emergency surgery to remove her stomach after drinking a cocktail containing liquid nitrogen.
Lancashire Police say the 18-year-old was out with friends in Lancaster on Thursday 4 October when it happened.
The woman is reported to have become breathless and developed severe stomach pain before being taken to Lancaster Royal Infirmary.
Officers say she would have died if doctors had not performed the operation.
The woman, from Heysham in Lancashire, was taken to hospital at 11pm.
She was diagnosed with a perforated, or pierced stomach. The 18-year-old is now in a serious but stable condition.
Lancashire Police have not named the place where she bought the cocktail, but say it has stopped selling it.
A statement said: "The premises involved have fully co-operated with all agencies and have suspended drinks involving liquid nitrogen.
"The investigation is still in its early stages and we are still interviewing witnesses to establish the full facts."
The force said they had been warning other bars in the town about what had happened.
Heston Blumenthal has popularised the use of liquid nitrogen in cooking, using it to make ice cream.
It is also used in medicine to remove unwanted skin, warts and pre-cancerous cells, while in industry it can be used as a coolant for things like computers.
Additionally it has been used in cryogenics, where scientists find what happens to materials at very cold temperatures.
