Sgt Paul Kear, of Melton Police, said: “We are aware there have been a number of incidents of lead thefts in the Melton area this month.
“It appears these are opportunist thieves who are targeting domestic properties and small businesses, taking small amounts of lead, it seems to sell on for scrap, but causing damage to properties and inconvenience and considerable expense to the people living in the properties.
“Neighbourhood officers are aware of the issues and are carrying out extra patrols in the area.
“Officers on the response teams – responding to 999 calls – are also aware of the increase in reports.
“We would encourage residents to stay vigilant and if they see anyone acting suspiciously around the front of a building with lead within reach please call 999.”
