Police fear ugly clashes outside Parramatta Mosque as anti-Islam group plans protest at building where 15-year-old gunman prayed before he shot a police accountant

Police fear a violent outbreak as tensions grow between far right nationalists and anti-Islamophobia groups who have planned coinciding protests outside Parramatta mosque following last week's fatal shooting.

A heavy police presence is expected on Marsden Street, in Sydney's west, on Friday evening after a group opposing multiculturalism organised a protest outside the mosque - the place of worship 15-year-old Farhad Jabar allegedly obtained the gun he used to shoot police employee Curtis Cheng.

'The Party for Freedom' have demanded the mosque formally 'reject terrorism and Sharia Law' after claiming the place of worship has 'come under the spell of hateful preachers' who spout 'vile' messages of 'terrorism and oppression'.

While a second group, 'No to Racism, No to Fascism, No to Islamophobia' have organised a counter rally to support the local Muslim community, who they say have fallen victim to 'opportunistic' anti-Muslim scare campaign. 

'Join us at this protest to let the neo-nazis and their racist pals in government know that there will never be room for racism and fascism on the streets of Sydney,' the pro-immigration group wrote on Facebook. 

Nick Folkes, organiser of the anti-Muslim rally, insists Islam is a religion of 'war' and claims protesting is 'the least we can do' after Friday's shocking attack on Parramatta police headquarters. 

In a wide ranging interview with Daily Mail Australia, Parramatta Mosque leader Neil El-Kadomi said attending the mosque did 'not radicalise people' and denied any links to terrorist groups.

Parramatta Mosque leader Neil El-Kadomi has categorically denied any links with terrorist groups 

The protests were sparked by 15-year-old gun Fahard Jabar who shot a police employee dead on Friday 

‘I mean… (if) somebody went into McDonalds, bought a hamburger, and while you’re working goes pop-pop-pop-pop [gun noises], is McDonalds in charge of him, of the act?, he said.

Mr El-Kadomi acknowledged that he has heard of the terrorist group Hizb-ut-Tahrir, but categorically denied any affiliation with them.

'I cannot deny I know Hizb-ut-Tahrir, because I hear it on the news everyday. But I'm not with them,' he explained.  

At the time of publication 739 people were invited to the anti-Muslim protests, with 91 confirming their attendance. 

More than 2,500 people have been invited to the counter rally, with around 295 people accepting the invitation.

The vast disparity in numbers may mirror protests that took place earlier this year in Melbourne and Sydney, where between 20 and 60 right-wing protesters - from Reclaim Australia and the United Patriots Front - clashed with around 200 pro-immigration activists.

Violence broke out when the two groups came face to face, with dozens of people requiring medical attention after police were forced to use capsicum spray to control the angry crowds.  

Police have warned that members of the public engaging in anti-social behaviour will not be tolerated.  

'NSW police want to remind members of the public against engaging in reprisal actions or inciting violence against any community group or individual,' a police spokesperson told Nine News.  

'As police, our message is that any act of violence, regardless of the motivation, will not be tolerated.'

While outspoken nationalists from The United Patriots Front - who refer to their counterparts as 'left wing unwashed grubs’ - were expected to attend Friday's event, the group announced that they would only be supporting a demonstration that opposes a mosque being built in Bendigo, organised for Saturday.

'We encourage all Australian people to be vigilant and stay smart; stay away from Parramatta Mosque and let the police do their job,' they said on Facebook. 

More than 20 members of the far-right group have uploaded pictures of themselves, holding a piece of paper with the time and date of the protest, along with the message 'rise without fear'.

This comes only days after the group staged a fake beheading out the front of local council chambers in response to plans for a local mosque.

A group of demonstrators from the far right group the United Patriots Front chopped a dummy's head off with a knife out the front of the City of Greater Bendigo council chambers at the weekend.

Fake blood spilled onto the floor in front of the council which has long been home to fiery debate over whether a mosque should be constructed in the regional city.

The small group of Caucasian men yelled 'Allahu Ackbar' and 'takbir' as they chopped the man's head off. 

Around five protesters gathered out the front of the building in a protest against the Bendigo mosque and, reportedly, in response to Friday's shooting in Parramatta

The protesters then paraded around the town waving Australian flags, striding past ladies' fashion store Sussans repeatedly chanting 'Aussie'.

UPF spokesman Blair Cottrell told The Age the stunt was in response to the mosque's approval and Friday's shooting of a NSW Police finance worker in Parramatta.
