Seven illegal immigrants have been found hiding in the back of a lorry parked at a service station on the M4 in Wiltshire.

The group of six men and a 15-year-old boy are all Afghan nationals, a spokesman for Wiltshire Police said.

They were discovered after noises were heard coming from the back of a lorry parked at Leigh Delamere services on Thursday evening.

They have been taken to Melksham police station to await immigration officials.
