Three Sydney gang members charged over the murder of a young man hacked to death with meat cleavers during a violent home invasion have been found guilty.

The jury in the Supreme Court murder trial of Mahdi Mir, 22, Mohammad Karimi, 25, and John Khoury, 32, returned guilty verdicts after just over one day of deliberations following a three-month trial.

The men were members of a gang, The United Brotherhood, which carried out a spate of vicious home invasions in 2010.

Four members of the gang broke into Kesley Burgess' home at Lurnea in south west Sydney on July 1, 2010, attacking him with meat cleavers as his mother begged them to kill her instead.
