'You are Satan': Incredible moment grieving widow of bikie boss Mick Hawi confronts a former best friend at a busy shopping centre after she testified at the Comanchero leader's murder trial - as footage emerges of their extraordinary public row

The grieving wife of a former bikie boss who died in a hail of bullets has become tangled in a bitter falling out with a former friend who gave evidence at his murder trial.

Mahmoud 'Mick' Hawi, former Comancheros national president, was shot dead in his black Mercedes parked outside a Fitness First gym in Rockdale, in Sydney's south on February 15, 2018.

Last month in the NSW Supreme Court two men were found not guilty of murdering Mr Hawi.

His wife, Carolina Gonzales bumped into her former close friend, Ophelia Haragli, at the Bankstown shopping centre last weekend.

Extraordinary footage showed them both rowing in the mall, as their row spilled out after weeks of warring on social media.

Ms Haragli gave evidence into the investigation of his murder, and told police Mr Hawi had extorted $500,000 from her cousin and another man, the Daily Telegraph reported.

During the tense encounter at the shopping mall, Ms Gonzales was seen pointing her finger at Ms Haragli with a furious look on her face. 

Photos of the interaction were shared to social media by both women but have since been deleted, according to the newspaper.

Tensions recently escalated into feuds online with Ms Haragli calling her ex-friend 'Satan' and sharing several angry Facebook posts.

She said that during their spat, Ms Gonzales had called her an 'attention seeker' with the encounter even being posted to Facebook in a live video.

'A shopping trip in Bankstown leads to these embarrassing and angst provoking scenes and me turning my head inside out frantically trying to work out which exit we might be ambushed at,' Ms Haragli wrote online.

'I'm proud to say I have a life and it's a damn ­worthy one and that if you just f**k off and leave me alone it's better for you.'

In older posts, Ms Haragli made digs at Ms Gonzales' personal life.

While giving a statement to police after Mr Hawi's death, Ms Haragli said she had befriended him and his wife back in 2009. 

But the relationship turned sour after Ms Haragli told police the former bikie had extorted the money. 

Mr Hawi was the former leader of the Comancheros bikie gang before he was shot in February, 2018

Just hours after the bikie was killed, the court heard Ms Gonzales had gone to Ms Haragli's home and threatened to kill her husband.

'I didn't mean it. I was angry, my husband had just died,' Ms Gonzales told the court. 

She also denied her husband extorted any money.

Two men, Yusuf Nazlioglu and Jamal Eljaidi, were found not guilty last month.

Meanwhile, Ahmad Doudar, 40 pleaded guilty to being an accessory after the fact to murder by assisting with disposing of an alleged getaway car.

Doudar was sentenced to four-and-a-half years behind bars.
