A police officer has been injured and a man shot at Narraweena.

Around 5.20pm this evening (Friday, 11 June) two male officers from the Northern Beaches Police Area Command were called to a home at Warringah Road, Narraweena.

Upon arrival they were approached by a man, understood to be in his 30s and who they believed may be armed with a knife. The man was at the address attempting to gain entry and discharging a fire extinguisher.

It is understood the man did not live at the address but NSW Police Assistant Commissioner Leanne McCusker said she did not believe it was a random attack and the man was known to the occupant of the property he was attempting to enter. The full video of the press conference with Asst Comm McCusker is below.

Police allege a violent confrontation broke out and the man threw a fire extinguisher at a male officer, striking him in the head. The officer, a 21-year-old male probationary constable, was also stabbed in his left hand causing a laceration.

It is understood police initially attempted to bring the situation under control using a taser, but it was ineffective in subduing the man, leading to speculation he may have been under the influence of drugs.

A shot was discharged by a second officer, and the man allegedly wielding the knife sustained a gunshot wound to his leg. It is understood the bullet struck the man in the thigh and passed through his leg.

Regaining control of the incident scene, police provided initial first aid to the man until the arrival of NSW Ambulance paramedics who took over care of the man and police officer. Neither injury is believed to be life-threatening.

The man with the gunshot wound was assessed and stabilised at the incident scene before he was taken under police guard to Royal North Shore Hospital in a stable condition.

The injured police officer was assessed and given initial treatment at the incident scene before being transported to Northern Beaches Hospital in a stable condition. The second police officer was also taken to hospital in a stable condition, it is understood he may have inhaled fire extinguisher particulate.

After initial assessments by intensive care paramedics at the incident scene, a rescue helicopter that had been called to land at nearby Beverley Job Park was deemed not to be necessary and released from the incident.

NSW Police have declared the event a critical incident and a senior critical incident team from the Hills Area Command will now investigate the circumstances surrounding the incident. The investigation will also be subject to an independent review.

Police are exploring whether the incident at Narraweena is related to the incident earlier in the afternoon at Manly, in which a man was stabbed. Police said they were unable to comment due to a critical incident being declared and ongoing investigations. However, Assistant Commissioner McCusker confirmed the man was known to police.
