Muslim groups have slammed “differing treatments” in police handling of the Bondi Junction stabbing attack and the stabbing of a bishop at a Sydney church, saying the disparate response has left the community traumatised and isolated.

Five teenage boys were charged on Thursday with terrorism offences connected to the stabbing of an Orthodox Christian leader in Wakeley last week.

The attack came just days after six people were killed by Joel Cauchi in a stabbing rampage at Westfield Bondi Junction.

The shopping centre attack was “quickly deemed a mental health issue” while the church incident was “classified as a terrorist act almost immediately”, Muslim groups, including the alliance of Australian Muslims and the Australian Muslim advocacy network, said on Friday.

Australian National Imams Council’s Ramia Abdo Sultan said the disparity in police response was a double standard and called for an inquiry into the processes leading up to the raids on the teenage boys.

“The differing treatments of two recent violent incidents, the senseless stabbing deaths at Bondi Junction and the tragic event at Wakeley church are stark,” Ms Sultan said.

The lawyer and communication relations advisor said the inconsistency has been exacerbated by police handling of a recent case where a device suspected to be a bomb was found attached to the car of a Sydney man who had erected a Palestinian flag outside his home.

“Yet this has not been labelled terrorism,” Sultan said.

“Such disparities in response create a perception of a double standard in law enforcement and judicial processes.”

Sultan said an “immediate and thorough inquiry” into the processes leading up to the raids would ensure transparency and accountability.

“The presumption that terrorism is inherently tied to religion is not only inaccurate but also harmful,” she said.

Five teenage boys, all under the age of 17, were arrested and charged following 13 raids at homes across Sydney and a week-long investigation into a group allegedly adhering to religiously motivated violent extremist ideology.

NSW Police said three of the five juveniles were charged with conspiring to engage in preparations for a terrorist act.

Two others, aged 14 and 17, were charged with possessing or controlling violent extremist material through a communication service.

Police said group members did not name specific targets but the ongoing threat and loose nature of the group, including some splinter groups, alarmed authorities.

They were allegedly connected to a 16-year-old boy charged with the stabbing of Assyrian bishop Mar Mari Emmanuel and priest Isaac Royel on April 15.

Sultan said the Muslim community had not been consulted before the police operations or raids.

“This lack of transparency exacerbates the distress within our community,” she said.

“There must be a commitment to meaningful engagement regarding this process with the community and to avoid sensationalism that can cause undue panic and a breakdown of social cohesion.”

The Lebanese Muslim Association urged police to share intelligence to help stamp out any extremism in the community.

Secretary Gamel Kheir said it was important for the community to stay united with authorities.

“We need to move on and work out how to resolve the ongoing issue of meeting these youths before they fall between the cracks,” he told AAP.

“We need to address why the social issues are there in the first place.

“Do we experience Bondi and Fairfield again and again? It’s not a Muslim issue any more.”
