Bikie's gun 'down girlfriend's underpants' A FINKS bikie accused of possessing a loaded gun allegedly found down the front of his girlfriend's underpants will remain behind bars. Refusing bail for Dylan Jessen on Friday, Justice Michael David concluded that the accusations against the 22-year-old were more than serious and bordered on the dangerous. His lawyer, David Edwardson SC, had asked the South Australian Supreme Court to review a decision made by a magistrate on Thursday to refuse bail. The Adelaide bikie had handed himself into police on Wednesday and was charged with possessing an unregistered revolver and removing its serial number. Jessen, who appeared via video link, had the word "Terror" tattooed across his left eyebrow and "Team" across his right, while the number 66 was tattooed on his left cheek. "Finks MC" was tattooed on his neck. Justice Edwardson was told the charges related to police attending an address occupied by Jessen and his then-girlfriend and finding the loaded gun down her underpants last November. Rachel Morden, for the crown, opposed bail, alleging Jessen's DNA was present in a "strong ratio" on the gun and ammunition had been found in the cupboard. Mr Edwardson said Jessen strenuously denied the charges and his co-accused, his former girlfriend, was granted bail in November. The most serious matter on Jessen's record was assaulting a police officer, for which he served five months, and he had no history of firearm offences, he said. Refusing bail, Justice Edwardson said he was not taking into account Jessen's Finks membership. Rather, he was concerned about the serious allegations of his having had a repeater pistol, loaded with ammunition, around the house. Further, the weapon was not licensed and its identification number had been removed. Jessen is due to return to Elizabeth Magistrates Court in April.
