A £2,000 reward is being offered for the return of four book-vending machines stolen in Essex.
The vending machines were stolen from a lorry in Essex
The machines, worth £10,000 each, were in a trailer attached to a lorry parked at PN Computer Services on High Street, Elsenham near Bishop's Stortford.
They were due to be delivered to Stansted Airport, but thieves took the trailer between Friday 14 and Monday 17 September.
Essex Police said they have few leads and want information from the public.
Pc Elaine Crow, from Essex Police said: "This is rather a strange theft. We have very few leads which is why we are looking for any information from witnesses or anyone who has since seen the trailer."
Novel Idea Vending, based in Limerick, Ireland, is offering a £2,000 reward following the recovery of the vending machines.
