Three more arrests have been made in relation to a series of Canterbury mail thefts.
Rolleston police Constable Liz Johnson said three teenagers, aged 17, 18 and 19, were arrested on Friday after police stopped their car in Hornby.
They were charged with stealing mail from letterboxes across the Selwyn District in the last few weeks.
They allegedly used details on the stolen mail to phone homeowners and convince them to hand over personal details that allowed thieves access to their bank accounts.
It is alleged $41,850 has been stolen from several accounts.
