Children are turning to shoplifting things like bread because of hunger, the police have told Newsround.
Inspector Andy Briers of Islington Police in London said: "They're not stealing sweets and chocolate and chewing gum, they're actually going out and stealing bread and food for themselves and their families."
He explained that they're tackling the problem by handing out food vouchers which can be swapped for three days' worth of food.
Charity Save The Children say that 3.5 million kids in the UK are living in poverty.
They found that one in eight children doesn't get a warm meal every day - apart from the one they might get at school.
