Leaving your home during hours of darkness, without putting a light on or drawing the curtains, is an open invitation to the opportunist criminal that there is no one at home.
Inspector Rachel Barrow, Eastbourne's Neighbourhood Policing Inspector, said, "It sounds simple advice, but when it is dark outside people don't always think to draw their curtains or leave a light on if they are going to be out.
"To the opportunist burglar, it is almost an invitation. A house that is in darkness is the easiest target.
"It doesn't take long for a burglar to get inside and steal property, particularly things that are easy to sell such as televisions, DVDs, computers, jewellery and money.
"Unfortunately, every year sees a spate of burglaries so please be vigilant.
"Trust your instincts. If you see anything suspicious let us know. This could be an unfamiliar vehicle cruising your road, a suspicious caller who may be asking for directions or trying to sell goods or a service, or a stranger approaching the rear of your neighbour's property."
