Lawyer Theo Magazis said his client was awaiting surgery for an injured leg and needed a medical examination while in custody.
“He requires a compression bandage which has been removed while he’s been in custody,” Mr Magazis said.
Mr Heil is due to return to court on Tuesday.
Two men arrested during Wednesday’s raids have been charged with the murder of fruiterer Paul Virgona, who was gunned down on the EastLink Freeway as he drove to work last year.
It is not alleged Mr Heil was involved in Mr Virgona’s death for which only Josh Rider and Aaron Ong have been charged.
Police raided a dozen properties linked to the Mongols on Wednesday, including a clubhouse in Port Melbourne where they found six guns and ammunition.
Josh Rider, 29, and Aaron Ong, 34, were arrested during the raids and charged with the execution-style murder of Mr Virgona.
The alleged Mongols bikies are accused of opening fire on the 46-year-old father as he drove to work on EastLink at Donvale during the early hours of November 9 last year. The duo are due to face court again on May 27.
They are accused of waiting for Mr Virgona to leave his family home in Croydon and following him in a stolen Mercedes-Benz sedan, before firing 11 rounds from a nine-millimetre semi-automatic handgun into the fruiterer’s van.
Police are yet to identify a link between the two accused killers and Mr Virgona. Whether Mr Virgona’s killing was a case of mistaken identity remains an open line of inquiry.
Assistant Commissioner Tess Walsh told a press conference on Wednesday that detectives were at pains to point out there was no evidence Mr Virgona or any of his family members had criminal or Mongols links.
“The victim has no criminal association and no association with the Mongols,” she said. “Mr Virgona has no criminal associates and there is nothing in his background that would suggest that anything he or his family have done have been part of the reason why he’s been the victim of this heinous crime.”
Police also raided the Mongols’ Ferntree Gully clubhouse, as well as the South Melbourne tattoo parlour co-owned by Mongols member Toby Mitchell and former Richmond footballer Jake King.
Mr Mitchell’s Southbank apartment was also raided. Mr King and Mr Mitchell are not accused of any involvement or wrongdoing.
Mr Rider is a long-time associate of Mitchell, the former Bandidos sergeant-in-arms who joined the Mongols in 2019.
A fourth man arrested during Wednesday’s raids has been charged with drug possession and will appear at Ringwood Magistrates Court on May 7.
