Shoppers say they have been left shocked after finding baby milk in security boxes and removed from shelves in a bid to deter thieves.
In some stores security tags - which have to be removed when products are paid for at the tills - have been wrapped around tins of formula milk powder. The devices, which set off an alarm at a shop's exit when anyone tries to remove the item without paying, are most commonly found on high-value producst like perfume, aftershave, and bottles of booze.
They are sometimes also used to try and prevent the theft of regularly shoplifted items such as cheese, meat and coffee. Yet some shoppers have said they were taken aback to see tags used on large milk tubs.
