Police have arrested two men as part of an eight-month investigation into the shooting murder of Mitat Rasimi in Dandenong.
Taskforce Sector detectives arrested the 26-year-old from Hallam and the 25-year-old from Hampton Park as part of eight house raids on the morning of Thursday 7 November.
The pair were to be interviewed by police.
The raids took place at two residences in Endeavour Hills as well as dwellings in Hampton Park, Hallam, Dandenong, Deer Park, Seaford and Narre Warren South from 5am.
Police from the Homicide Squad, the anti-outlaw motorcycle gang Echo Taskforce, the Special Operations Group, Dog Squad as well as Australian Federal Police members were involved.
Mr Rasimi, 51, was fatally shot in a car outside his home in Dawn Avenue on the evening of Sunday 3 March.
The father-of-four, with reported underworld links, was found dead in his car which rolled forward and crashed into a pole.
In an effort to crack the case in recent weeks, police publicly released footage of an orange Ford Ranger ute and a man walking to and from the vehicle.
The ute had been found at McMahens Road in Bangholme 30 minutes after the shooting.
A man was believed to have attempted to set the ute alight before being disturbed by a witness.
Taskforce Sector was formed this year to investigate links between several fatal shootings including the killing of two people outside a Prahran nightclub in April.
