In May 2015, ex-Philippine National Police (PNP) officer Jun A. Malban, alias Michael Zoo, was arrested in Kota Kinabalu, Malaysia, for the crime of "Kidnapping for Ransom" after Rodwell identified him as the negotiator/spokesperson. Further PNP investigation revealed that Malban is the cousin of Abu Sayyaf leaders Khair and Borhan Mundos (both of whom were arrested in 2014). The director of the Anti-Kidnapping Group (AKG) stated that Malban's arrest resulted from close co-ordination by the PNP, National Bureau of Investigation (Philippines) and Presidential Anti-Organized Crime Commission with the Malaysian counterparts and through Interpol. In January 2018, Rodwell attended a court hearing for Malban and others in Ipil, Zamboanga Sibugay, pursuant to a Supreme Court petition to transfer his case for security reasons to a court in either Manila or Zamboanga City.
