A POLICE officer has been rushed to hospital in a serious condition after reportedly being stabbed in the chest at a pub in Sydney.
The 45-year-old senior detective was wounded by wanted child sex offender Nick Newman at about 3.10pm at Maroubra Junction Hotel on Anzac Parade.
Dramatic video shot by a witness at the scene showed officers with guns draw at a back entrance to the pub, before entering in combat stance.
'Our friends were inside and we heard the shots so we hurried to see what was going on.
"I reckon [there were] about four, five shots, easy, "bang, bang, bang, bang, bang".
The westbound lanes of nearby Maroubra Road have been closed because of a NSW Police operation, Live Sydney Traffic tweeted on Friday.
NSW Police stepped up their presence at the scene of the incident with dozens more police officers and several ambulances arriving before senior police declared the shooting a Critical Incident.
'I went outside and there were three or four ambulances and a whole bunch of police cars.
The officers who shot Newman were "traumatised", according to Mr Walton, who said police were "very concerned" about the injured detective sergeant's condition.
Noel Whelan is staying at the pub, and was nearby at the time of the incident.
'I knew something was wrong when the police came pouring in.
Witnesses Mackenzie Gibbs and John Mackawski were walking to the Maroubra Junction Hotel, dressed in Australia Day costumes as an Aussie bogan and Crocodile Dundee, when they saw a man covered in blood inside.
"They were pushing us out the door, telling us to get out, it was a crime scene".
"You can't share some of the things that we see with people", he said.
A critical incident team from the Homicide Squad has launched an investigation into the stabbing and subsequent shooting.
Police Association New South Wales President Scott Weber says he feels for the officer and his family and his thoughts and prayers are with the officer and his family.
The investigation will be independently reviewed and a report prepared for the coroner.
