Police have charged Ibrahem Hamze with multiple offences, after extraditing the Sydney underworld figure from Queensland overnight.
The charges include soliciting a murder, shooting at someone "with intent to murder", and several firearms offences.
It's believed detectives have repeatedly warned Mr Hamze, 27, who has survived multiple execution attempts, his life is in danger.
The arrest is the latest incident in the extended feud between the Alameddine and Hamzy — sometimes spelt Hamze — families.
He was detained on the Gold Coast on Monday, before a Queensland magistrate granted NSW Police's extradition request.
At Bankstown Police Station late yesterday, he was charged with more than a dozen offences, most of which relate to his alleged role in a public place shooting outside a gym at Prospect, in Sydney's west, late last year.
On November 29, a 33-year-old man was shot in the leg.
CCTV captured four men walking toward the gym's entrance when a series of bullets were fired towards them, with several shots striking the staircase and building.
Several bullets also entered a daycare centre next to the gym and narrowly missed children and staff inside.
A dark-coloured Mazda was shown speeding from the scene, with the vehicle later found burnt out Augusta Street, Blacktown.
Two men, aged 23 and 19, were arrested in December by strike force detectives and charged with offences including shoot with intent to murder.
At the time, Superintendent Steve Egginton from NSW Police said: "A number of the bullets that were fired from these offenders have actually entered the gym and posed a significant danger to people inside, including children."
Additional offences Mr Hamze was charged with relate to allegations of his involvement in the kidnapping, detainment, and assault of a 24-year-old man in September 2021.
Police allege a man was approached in a Merrylands street on September 18 and forced into the back of a white van.
The man was allegedly detained in a vacant unit at Auburn for several hours before being released with a stab wound to his shoulder.
The ABC understands the alleged victim promised the Hamzy network that he would provide fake COVID-19 vaccination certificates for a sum of money.
Police will allege he was kidnapped after he pocketed the payment but never provided the certificates.
Mr Hamze is one of seven men who have now been charged over the alleged kidnapping.
Four men were arrested yesterday after raids on homes in Condell Park and Thirlmere, where officers allegedly seized items relevant to the investigation.
Police then swooped on Ahmad El-Chamy and Haissam Hamzy, both 27, on Dargan Street in Yagoona about 2.15pm.
Bilal El-Chamy, 21, and Tareek Hamzy, 24, were later arrested at Bankstown Police Station.
All four men were charged with take/detain in company with intent to get advantage occasion actual bodily harm.
Those four men, and Mr Hamze, were refused bail to appear at Parramatta Bail Court today.
Tareek Hamzy, and brothers Ahmad El-Chamy and Bilal El-Chamy, did not apply for bail during a brief appearance.
The court heard the trio would apply for bail in the same court on Friday.
Haissam Hamzy and Ibrahem Hamze were also formally refused bail after not applying for release.
Their lawyer Fadi Abbas said the two men would not be applying for bail at this stage.
They will next appear at Central Local Court on April 7.
