killing of underworld figure Abdul Darwiche and a string of bikie-related drive-by shootings has put the police on high alert. An internal memo, penned by south-west region commander Assistant Commissioner Frank Menelli, has been distributed to officers in trouble-prone areas, urging them to take extra care. The shooting of Mr Darwiche, 37, at a Bass Hill service station has rocked Sydney's Islamic community and sparked fears of imminent reprisal attacks. As detectives work overtime to calm tensions, a parallel feud among outlaw motorcycle gangs has broken out, with fresh attacks around Blacktown. "I thought it was appropriate,'' he said. "I worry about my officers and I tell them to be careful, but I haven't told anyone to back down.''
Mr Menelli said the fresh violence, coupled with events that have seen officers injured in the last week, prompted him to issue the memo. "Bearing in mind the current issues relating to OCMGs (Outlaw Motorcycle Gangs) and other tensions, I told them to make sure they're aware of officer safety when dealing with people,'' he said. Police have praised the Islamic community for being forthcoming with information and working with detectives to further their investigations. Immediately after Mr Darwiche's death, officers met with a wall of silence from family members, who refused to reveal who they thought was responsible. It has emerged that, to ease tensions, a senior officer ushered key family members away from the crime scene to a motel instead of a police station. There, after booking a room, calming tensions and ordering coffee, he gained their trust and asked them to privately explain what was unfolding. Within two hours, the entire story and the gravity of the situation was laid on the table. Detectives believe Mr Darwiche's shooting can be linked to the murder of 25-year-old Ahmad Fadha in 2003. Mr Fadha was an associate of the Razzak family, which at the time was involved in a bitter turf war with the Darwiches over drugs. Late last week, police formally issued a plea for Ahmad Fahda's younger brother, Mohammed "Blackie'' Fahda, 24, to come forward about the shooting. Mohammed Fahda remains in hiding, but is not thought to have fled the country.
A detective close to the investigation said an alert had been circulated through agencies, to ensure police are contacted if Mr Fadha makes an attempt to board a flight out of Australia. Police strike force teams were quickly assembled once investigators established the high likelihood of retaliatory attacks. Detectives are fearful that imminent reprisals are on the cards. Last week Mr Darwiche's elder brother, Michael, 40, and another man, Michael Darwick, 36, were arrested at Punchbowl. When police searched their BMW, they allegedly found a map, a gun and names and addresses of Fahda family members. Later that night, two drive-by shootings, which may be linked to the Notorious bikie gang, occurred near Blacktown.
The gang is believed to be linked to the bombing of a Hells Angels clubhouse at Petersham, as well as a shooting at a new Nomads clubhouse in Chalder Ave, Marrickville last month. Marrickville police have made little progress into the Nomads shooting because of the "code of silence'' strictly adhered to by the bikies.
They have approached Marrickville Council about shutting down the venue, which police allege was set up as a car-repair shop but is being used for late-night parties.
