Police wish to speak to these four people

Police were called to PC World after three men and a woman attempted to take two units but were disturbed.

The group managed to leave with one �250 sat-nav, and four days later a man and a woman returned to the store and took another four TomTom units.

The police have released CCTV footage showing four people leaving the store.

Officers would like to hear from anyone who may have been offered the navigation sets.
