RT Article T1 Co-offending networks among members of outlaw motorcycle gangs across types of crime JF Trends in organized crime VO 27 IS 3 SP 263 OP 285 A1 Bright, David A2 Sadewo, Giovanni A2 Cubitt, Timothy I. C. A2 Dowling, Christopher A2 Morgan, Anthony 1980- LA English YR 2024 UL https://krimdok.uni-tuebingen.de/Record/1904143466 AB Outlaw motorcycle gangs (OMCGs) have become synonymous with organised crime through engagement in criminal activities including illicit drug production and distribution, firearms trafficking, and serious violent crime. These crimes contribute significant social and economic harms in countries that feature a presence from these groups. The current paper uses network analytics to analyse the extent of co-offending within and across established clubs in Australia, including the relative involvement of senior, or office bearing, members. The majority of affiliates in this sample co-offended with another OMCG affiliate within the sample period, with office bearers, members, nominees and associates represented proportionally among co-offending networks to in the sample at large. However, within these clubs, criminal activities were conducted in small cliques or components of affiliates. This research supports the role of OMCGs as important facilitators of crime, and the role of co-offending in the criminal offending of affiliates. The findings hold important implications for understanding how offending is organised among OMCGs, differences between groups, differing levels of engagement from the club hierarchy.
