Policeman dead after attack

A SENIOR police officer has been killed after he was hit on the back of the head in outer western Sydney.

Detective Inspector Bryson Anderson, 45, was attacked at a semi-rural property in the suburb of Oakville, about 50 kilometres north-west of Sydney, just after 2pm on Thursday.

A 19-year-old man and a 42-year-old woman were arrested at the scene and were being questioned by police.

Officers were called to the property after neighbours complained about arrows being fired into their yard from a crossbow.

The situation escalated to the point where 11 officers had to be called to the home.

At one stage officers were attacked by dogs. It appears that Detective Inspector Anderson became separated from the other officers and that was when he was attacked. He was rushed to Hawkesbury District Hospital but was pronounced dead a short time later.

The man arrested at the scene lived at the home where the altercation took place. Neighbours said he regularly hunted with a crossbow.

Speaking outside the hospital on Thursday night, Police Commissioner Andrew Scipione paid tribute to the senior detective, describing the father of three as an ''excellent officer and a damn good bloke''.
