People are being urged by police to lock their doors overnight after incidents where car keys and personal items have been taken from homes.
Devon and Cornwall Police said homes across south Devon including Torquay, Newton Abbot, Teignmouth and Paignton had been targeted.
The force said officers had made several arrests in relation to burglary and vehicle theft, with some offenders already convicted and facing sentencing next year.
Det Sgt Jason Parsons, from south Devon criminal investigation department (CID) team, said: “Both urban and rural residents have fallen victim to these offences and remembering to lock doors, especially at night, is very important.”
