Thieves stole cigarettes worth £1,500 from a delivery lorry in Crawley.
Sussex Police said the lorry was in Balcombe Road, on its way to a Co-op store in Maidenbower, when the lorry was broken into.
The theft happened on Friday (June 6) between 12.30pm and 1.05pm but was not reported until the next day (June 7).
