A man is in custody after he allegedly started a fire inside a house in Auckland's Titirangi and threw things from the balcony.
Police were called to a property on Waima Crescent at around midnight following a report of a family harm incident.
Detective Senior Sergeant Marcia Murray said when police arrived, the occupants came out of the address except for one man, who said he had a firearm.
When it sounded like damage was being done inside the property, a cordon was set up around the address, Murray said.
Neighbouring properties were also evacuated by police as a precaution.
The man remained inside the house and was observed throwing items from the balcony.
The man then allegedly started a fire inside the house and jumped off the balcony where he was subsequently taken into custody.
The man received minor injuries during the incident and was taken to hospital as a precaution.
He is expected to face charges and is expected to be appearing in court later today.
Enquiries are ongoing and a scene guard remains in place this morning.
