Gas stolen from Wisbech ambulance station
Cylinders of so-called laughing gas have been stolen from an ambulance station in Cambridgeshire.
Thieves took three canisters of entonox from a cupboard at the Wisbech station on Tuesday night.
A spokesman for the East of England Ambulance Service said that if used incorrectly, the gas could lead to brain damage.
About 50 canisters of the gas were stolen from three ambulance stations in Suffolk earlier in the year.
The service has applied for planning permission to put up security fencing at the stations targeted.
Sean McAuley, duty operations manager for the East of England Ambulance Service in west Norfolk, said: "A strong warning should be sent out as the people who target ambulance stations for these canisters are actually dealing with a dangerous gas when used incorrectly.
"If used to get high, they run the risk of serious brain damage and it can become addictive, leading to major disabilities."
