Two teenagers have been arrested after a vape store was burgled in Blenheim early on Friday morning.
The store has been targeted three times in one week with burglaries reported on March 16, 17 and 24.
The two teens have been referred to Youth Aid and police are working to identify others involved. Police are investigating whether the burglaries are linked.
Two further people were arrested on Sunday after police discovered several items relating to an earlier burglary while carrying out a search warrant at a Blenheim house.
Relieving area response manager for Marlborough Detective Sergeant Lindsay Tilbury said police are working with the teens and their families.
"Police will be increasing our visibility and patrols in the area where this business was targeted.
"We acknowledge how upsetting this series of offences has been for them," Detective Tilbury said.
"Anyone with information relating to these incidents is asked to contact Police on 105 quoting file number 230324/1513."
