Drug dealer
Police believe that Dibra and an old friendRocco Arico, were partners in selling and distributing cocaine, ecstasy and amphetamines. They were regular faces at the Dome nightclub in Prahran, Melbourne, as well as a Crown Casino nightclub. The Purana Taskforce have stated on numerous occasions that Dibra was associated with several Melbourne underworld figures, including Mark Moran, Jason Moran, Andrew Veniamin, Carl Williams and Nik Radev at different times and it is believed that these associations pertained to high-volume drug supply. In 1998, a bouncer was shot outside the Dome Nightclub in Prahran. Dibra was the principal suspect in the shooting and it is believed that the shooting followed a dispute relating to drug supply.

At the time, police had bugged Dibra's house and car, seeking information in relation to the Dome bouncer shooting. The police subsequently raided Dibra's Taylors Lakes house, where the victim was still locked inside the boot. Dibra and Arico were charged with a variety of offences over the incident.
