THE drug dealer who dobbed in crime boss Tony Mokbel is likely to be paid Victoria's first $1 million reward. He has already escaped being charged over his prominent role in Mokbel's gang, which included helping Mokbel organise a false passport to flee Australia. But veteran underworld figure Billy Longley yesterday warned the "grass" who fingered Mokbel would have to keep looking over his shoulder for the rest of his life. "A lot of people have gone to jail because of him, including Mokbel," Mr Longley said. "Such people have long memories and will want revenge." The previous biggest amount paid out by Victoria Police was a $100,000 reward in 1991. There are nine other $1 million rewards up for grabs at present. The police informer in the Mokbel case, codenamed 3030, was a key member of Mokbel's drug syndicate, known as The Company, as well as a drug user.

Purana gangland killing taskforce detectives persuaded 3030 to work for them inside The Company. Information provided by 3030 resulted in multiple arrests of members of The Company, including Mokbel in Greece on June 5, 2007. The informer is a significant step closer to being paid the $1 million, as Mokbel is due in court tomorrow for a pre-sentence hearing. Mokbel pleaded guilty in April to drug charges relating to his masterminding The Company while on the run in Victoria and Greece. A Victoria Police spokesman yesterday confirmed the process of deciding on the reward would begin at the end of a 28-day appeal period after Mokbel's sentencing. Supreme Court judge Justice Betty King already has described 3030's assistance to police as "invaluable". And police have paid tribute to 3030, saying he played a vital role in helping them to locate and arrest Mokbel. Apart from providing telephone numbers so police could bug phones of Company members, including Mokbel's, 3030 helped identify people in The Company's business as well as the houses, hotels and storages they were using. Information provided to Purana by 3030 enabled officers to put recording and listening devices in The Company's cars, houses and storages, as well as bug phones. He also assisted police in introducing undercover operatives into The Company. With 3030's co-operation, Purana detectives were able to find Mokbel and arrest nine of The Company gang members in Melbourne on the same day Mokbel was picked up in Greece. Raids on Victorian properties associated with The Company led to the seizure of amphetamines, cocaine, precursor chemicals used to make amphetamines, drug-making equipment valued at more than $500,000, and almost $800,000 in cash. The informer also helped police to identify properties The Company bought with drug money, which enabled their seizure. Lawyers acting for Joseph Mansour, one of The Company members convicted as a result of 3030 turning police informer, queried the lack of charges against 3030. In jailing Mansour for 10 years, Justice King said: "Your counsel referred to the fact 3030 is not charged in respect of these activities, which is not surprising, as a number of these activities that he undertook were at the behest of the police to gather evidence. "His assistance in identifying and breaking this very large conspiracy could be described as invaluable."
