Opportunistic thieves struck a property after a window was left ajar in the hot weather.

At 1am on June 17 people in a property in Trafalgar Close, Peacehaven, went to bed, leaving windows slightly open and a purse on the sill. Five hours later it was missing.

At 2.15am the same day a man, 18-25, was seen examining a purse in Heathy Brow, opposite Abbey Close, Peacehaven.

Realising he was being watched he ran off, dropping the purse which was later identified as the one stolen from Trafalgar Close.

Anyone else who saw the man or any suspicious activity in the area during the early hours is asked to phone Sussex Police on 101 or email 101@sussex.pnn.police.uk, quoting serial 450 of 18/6.

Sussex Police are offering these tips to deal with the risk of thefts in the warm weather.

- Keep all wallets, purses, credit cards, car keys and other valuables secure and out of sight.
- If leaving the house empty or a room unoccupied - even when just in the garden - lock all doors and windows, including fanlights. Be especially careful about those on the ground floor and above flat roof areas.
- Lock garden tools and ladders in a shed or garage after use. They could be used to break into your home or that of your neighbours if left lying around.
- Double check fences and boundaries to make sure they keep intruders out.
- If leaving windows open while asleep, fit window restrictors so they cannot be fully opened, or make sure they are not large enough to allow access.
- Fit outside security lighting or a visible alarm to help deter burglars.
