Multiple Attacks On Police Officers Within 15 Hours

Four people have been charged over the alleged assaults of five NSW police officers within hours.

In the latest incident, three officers were assaulted after attending a house fire in Sydney's west on Tuesday night.

Emergency services were called to a granny flat at the back of a home on Centenary Road in South Wentworthville at about 9.30pm, to find it well alight.

The blaze was extinguished and while no one suffered serious injury, one woman, 37, at the property was treated for smoke inhalation.

Checks revealed she had two outstanding warrants for assault, resisting police, intimidating police, and making vexatious phonecalls.

When officers tried to arrest her, she allegedly scratched one officer and kicked another multiple times.

She was taken to Westmead Hospital for treatment where she allegedly spat in the face of a third officer.

She's since been discharged from hospital and charged with three counts of assault while her warrants were also executed.

The alleged attack came just five hours after a police officer was punched in the face and kicked by a teenager at a shopping centre in Sydney's north.

The female senior constable and another officer were attempting to move on a group of teenagers at about 4.30pm Tuesday afternoon when the girl, 14, allegedly lashed out.

She was arrested at the scene, charged with assault and resisting an officer and was bailed to front a children's court next month.

The constable didn't need to go to hospital but was treated for soreness to her face and arm.

Earlier that day, Constable Jacob Vella was slashed in the neck and arms in Sydney's south-west.

He was one of two officers serving an arrest warrant in Sadleir just before 7am when they were confronted.

The weapon used was a "crude homemade weapon" made from a steel shaft on the end of a wooden stick, NSW Police Assistant Commissioner Peter Thurtell said.

A father and son have been charged.

The younger, 27, is accused of a number of offences including wounding a person with intent to resist arrest and assault.

The older man, 58, has been charged with use offensive weapon to prevent lawful detention, assault officer in execution of duty, and the outstanding warrant.

NSW Police Association president Tony King told 10 daily that the five assaults are disturbing.

"While the job of Policing in this State is unpredictable and dangerous, the women and men of the NSW Police Force do not put on their uniforms to be assaulted in the line of duty on routine jobs."

NSW Police have refused to comment.
