A number of people are expected to be charged after Sydney police attempting to disrupt what they say were planned illegal climate change protests were allegedly set upon.
Officers were carrying out investigations around a property at Colo Valley on Sunday when their vehicle was surrounded by a group who shoved them and let down tyres, Detective Superintendent Paul Dunstan says.
The police, who were attached to Strike Force Guard, were approached by a number of people who set about circling them as they moved towards the vehicle," he said.
"They pushed, shoved, jostled the police before they managed to enter the vehicle, at which point a group of people commenced damaging the vehicle, letting down the tyres and preventing the vehicle from leaving the area.
"The police fortunately managed to leave the area after a struggle and some time ensued."
Supt Dunstan said the force would not tolerate officers being manhandled under any circumstances.
"Those police that were attacked by that group this morning feared for their lives," he said.
"They called for urgent assistance and police from all over Sydney metropolitan area responded to assist and provide aid."
Police said earlier the officers had been assisted by specialist units including PolAir, the dog unit, riot squad and police rescue.
The operation was carried out at a camp occupied by members of climate activist group Blockade Australia, according to the Sydney Morning Herald.
Blockade Australia said in a social media post their camp had been the target of a police raid, describing the group as "nonviolent climate defenders".
Officers were in the area after receiving information a group of about 30 to 40 were gathering to prepare for upcoming protests, Supt Dunstan said.
Police intended to carry out investigations at the property but the activity brought their plans forward.
"We believe the group was engaging in behaviour, planning and preparing to conduct the extreme forms of protest that this group has conducted previously," he said.
"Practising, rehearsing and constructing items to conduct similar methods of protest they conducted during March protest activity, where you saw at Port Botany, elaborate objects being formed and used and put in the middle of the roadways to ultimately disrupt vehicle activity in trains in and around the city area."
Supt Dunstan said police remained at Colo Valley and had executed a search warrant, with further arrests and charges expected after two people were earlier taken into custody.
"This is not traditional protest activity. This is criminal activity," he said.
"There are a number of ways to conduct lawful protests.
"In fact, we conduct hundreds, if not thousands of protests in and around the Sydney CBD each year.
"What this group is engaging in is without doubt criminal activity, and hence the police response."
