THURSDAY MAY 7

They have a search warrant under the Misuse of Drugs Act and are looking for cannabis.

They are unarmed and without stab-proof vests as they have no intelligence that Molenaar - who has two minor previous convictions - might have guns.

Molenaar is out walking his dog so the officers are let in by his partner Delwyn Keefe.

They find a room set up to grow hydroponic cannabis with several plants in it.

Mr Snee stays upstairs while the others go down to the garage area and find packages of dried cannabis and a sawn-off shotgun.

Mr Diver goes back up to tell Mr Snee what they have found. When he gets there he finds Molenaar confronting Mr Snee with a sawn-off rifle.

Molenaar opens fire without warning or provocation. The three officers make it out of the house and head towards the street.

- in the left forearm, the upper torso and the lower torso. Both torso shots are fatal, and kill him instantly.

Molenaar runs down to the street and tries to shoot Mr Miller and Mr Diver as they drag themselves up Chaucer Rd, a steep hill known as "Breakneck".

Lenny Holmwood, a friend of Molenaar, arrives. He grapples with Molenaar, in an act of bravery that police say saved the wounded officers' lives.

. Despite being grievously injured, he manages to drag himself down the hill and takes cover behind a wall.

Molenaar also fires at motorists passing by, ambulance officers and police who try to go the aid of the stricken officers. Police say these shots are classified as "attempted murder".

Mr Diver takes refuge in a nearby house where he is helped by the occupant and police.

Mr Miller is pulled to safety by one of the first police officers on the scene, Detective Sergeant Tim Smith, and two civilians, while under fire. Police say their actions are heroic.

Inquiry head Detective Superintendent Rod Drew describes this hour as "a very frightening and dangerous situation, involving general murderous intent by the gunman Jan Molenaar". He says it is also characterised by the "amazing courage" of those who helped while the officers lay in the street.

At some point Molenaar lets his partner Ms Keefe leave.

Police fire what they say are their only two gunshots of the operation.

This comes after Molenaar fires

at armed offenders squad members near the house.

Molenaar points a rifle from behind a partially open door on the deck of his house.

A police officer fires the two shots at where he is believed to be standing and hits him. Molenaar retreats inside and there is a temporary lull in the shooting. Later in the day he tells police officers and family he was hit, but refuses to say where or the extent of the wound.

Mr Drew says the officer's actions in shooting are "fully justified". He complied with the law of self defence and defence of others. The shooting is also within police regulations.
