Police arrested a number of people on suspicion of theft from unattended motor vehicles overnight.
Police sergeant Andy Kneen said: ‘We have had reports of such thefts from both the north and south of the island over the past few days.
‘Police have recovered property during the course of this inquiry which we believe is stolen.
‘We are currently matching property to reported crime, and where we have matches, contacting aggrieved parties in an effort to identify the property.’
He said colleagues from CID were interviewing the suspected persons.
He added: ‘If you believe that property of any sort has been taken from your car, please contact your local police station. We think that we are holding items that have not yet been reported. Please continue to be vigilant and lock your cars and houses.’
