Two young serial offenders were arrested on Thursday after stealing from unlocked cars in Kuripuni.
Sergeant Mike Sutton said the two boys, aged 12 and 15, were known to police for previous thefts. "There are certainly a number of occasions that they've been involved with the police.
"Mostly [for] theft or damage of property," Mr Sutton said.
He said police were concerned about the young ages of the offenders, particularly the 12-year-old.
"I know that the police and other agencies are working with these families to support them and try and work out what is the cause of their offending so we can put some sort of prevention around that to stop it happening in the future," he said.
