Notorious Sydney Brothers 4 Life gangster Bassam Hamzy is found guilty of running drugs from inside one of Australia's toughest jails

The boss of notorious Sydney gang Brothers 4 Life has been found guilty of running a drug syndicate from inside one of Australia's most heavily guarded prisons. 

A three-week trial wrapped up last week against Bassam Hamzy, 45, with the jurors delivering their verdict on Friday after a week of deliberations. 

He has been found guilty of one count of commercial drug supply and one count of knowingly dealing with the proceeds of crime, reports The Daily Telegraph. 

Hamzy's cell is within the high risk inmate unit of Goulburn's Supermax jail, but he was able to still run the meth operation by using code words with fellow prisoners and drug runners. 

He has been in jail for more than two decades for various offences including shooting a teenager dead outside a Sydney nightclub. 

Hamzy had already been to trial for the meth syndicate in 2023 but jurors were unable to reach a verdict and so a retrial was held this month. 

Prosecutors told the court 450g worth of methylamphetamine had been sold in Wollongong between October 2017 and February 2018 in deals co-ordinated by Hamzy. 

Two men involved in those deals, who were members of Brothers 4 Life, would later give evidence against him in court.

They are known only as 'Witness A' and 'Witness I' for their own protection. 

The court heard both men were given indemnity from prosecution in exchange for their testimony. 

Lawyers for Hamzy argued at least one of the men had turned on him for no other reason than it benefitted him, however, the jury did not buy it.

The court heard Hamzy received $14,000 for the drug deals.

He is serving sentences for unconnected offences until at least 2035 and will return to court in August for sentencing on the drug charges.
