Thousands of pounds worth of televisions were stolen from a lorry parked in Daventry in the early hours of yesterday morning (Thursday, 5 November).
The lorry had been parked overnight in Royal Oak Way North and sometime between 4am and 4.30am, while the driver was asleep in the cab, the offenders broke into the back of the lorry.
The driver woke up hearing noises and saw another vehicle parked behind his. It is believed the offenders loaded the stolen TVs into the other vehicle, described as a white, 7.5 tonne lorry.
Officers are appealing for anyone who may have seen anything suspicious in the area around the time of the theft to contact them.
Witnesses, or anyone with information about the stolen property, are asked to call Northamptonshire Police on 101.
