COMANCHERO bikie who kept his membership a secret from his father has become the eleventh man to be sentenced over Sydney's fatal airport brawl.

 Zoran Kisacanin, 25, was found not guilty of murder or manslaughter last November, but guilty of riot and affray in relation to the March 2009 brawl. Anthony Zervas, the brother of Hells Angel member Peter Zervas, was killed during the violence involving the rival motorcycle gangs. Justice Robert Allan Hulme jailed Kisacanin in the NSW Supreme Court for at least three years two months and a maximum of five years and three months. "The Comancheros and Hells Angels motorcycle gangs were, in effect, at war with each other," the judge said. "The offender was a nominee member of the Comancheros. "He was subject to its strict rules requiring loyalty and prohibiting cowardice." The judge said Kisacanin played a role in the fighting - which generally involved wrestling, punching and kicking - and also picked up a bollard. But there was no evidence as to what he did with it. The judge said the participants in the riot were prepared to "engage in wanton and significant violence regardless of the presence of many airline and airport staff and members of the public". In an affidavit, Kisacanin said he became involved with the Comancheros after meeting members at a local gym. He said that the gang "sounded like good fun hanging out with the guys and being part of a brotherhood". As his mother and brother were in Serbia, his only family in Australia was his father and he kept his involvement secret from him. The judge noted Kisacanin has been housed with his Comanchero colleagues in jail, saying he "had no idea what to do if (he) was alone in prison". After promising to cease association with the club on his release, his father has agreed to let him live and work with him in a painting business. Comanchero national president Mick Hawi is yet to be sentenced after being found guilty of murder, while another club member is to be sentenced for manslaughter in March. Eight other Comancheros and two Hells Angels members have already been sentenced for their roles in the brawl.
