Two men in Basingstoke have needed hospital treatment overnight after apparently taking drugs meant for animals.
Hampshire Police say it could be linked to drugs that were stolen from a veterinary clinic in Worting Road between 8.30pm on 29 June and 5.55am on 30 June.
A man in his 50s was taken to hospital at around 7.20pm yesterday evening (30 June) and is said to be in a serious condition in intensive care.
Officers have now revealed a second man, in his 40s, was taken to hospital at around midnight, but has since been discharged.
Police are reminding people that taking medication that isn't prescribed for you and isn't intended for human use could have a detrimental impact on your health.
Officers are especially warning about a liquid substance that comes in a bottle branded "Iso-Flo" and contains Isoflurance, which they say can prove life-threatening if inhaled, consumed orally or inject.
Anyone who has taken animal medication to knows someone who has is urged to seek medical attention immediately.

A 36-year-old man from Basingstoke has since been arrested in connection with the incident and remains in police custody.
