An 18-year-old man has been charged in Sydney after detectives alleged he was a key player in a high-profile organised criminal network linked to plans involving murder, kidnapping, arson and illegal firearm supply.

NSW Police said Taskforce Falcon detectives arrested the man at Sydney International Airport in Mascot at about 3:30pm on Tuesday, 6 October 2026, following an extensive investigation into an encrypted communications device seized during an earlier crime-scene investigation in Sydney's north-west.

The investigation, known as Strike Force Devion, was established in September 2026 after detectives obtained and examined a Dedicated Encrypted Criminal Communications Device (DECCD). Police allege forensic examination of the device uncovered evidence connected to a range of serious criminal activities.

According to investigators, the material allegedly included evidence relating to conspiracies to commit murder, kidnappings and arson offences, as well as multiple alleged firearm-supply activities. Police subsequently carried out extensive inquiries to identify people allegedly connected with the criminal network.

The teenager was arrested with assistance from the Australian Federal Police and taken to Mascot Police Station. Police then charged him with 10 offences.

The charges include allegations of conspiring or agreeing to murder, encouraging or attempting to persuade another person to commit murder, directing the activities of a criminal group and possessing a dedicated encrypted criminal communication device for serious criminal activity. He was also charged with allegedly recruiting another person to assist in criminal activity and an alleged conspiracy involving the detention of a person with the intention of committing a serious indictable offence.

Two of the charges relate to the alleged supply of pistols to people not authorised to possess them. The remaining charges include two allegations concerning a conspiracy to recklessly destroy or damage business premises by fire.

Police said the investigation remains part of a broader effort to identify and disrupt organised criminal activity. Encrypted communication devices can be significant evidence in organised-crime investigations because investigators may use information recovered from them to identify relationships, communications and alleged criminal plans.

The accused man was refused bail and was scheduled to appear before Bail Division Court 7 on Wednesday, 7 October 2026.

NSW Police have urged anyone with information that could assist investigations into organised criminal activity to contact Crime Stoppers. Police also reminded the public not to submit information through police social-media pages.

The allegations against the 18-year-old have not been proven in court. He is entitled to the presumption of innocence, and the charges will now proceed through the NSW court system.

The investigation is continuing, and further arrests or charges could follow as detectives examine the alleged criminal network and the information recovered from the encrypted device.
