South Jakarta police arrested Pvt. Efrizal, a 31-year-old marine stationed at Marine Corps headquarters in Cilandak, on the afternoon of Saturday 4 March 2006 after he led them on a high-speed chase along local toll roads.[1] Officers found about 199 kilograms of marijuana in his car, with an estimated street value of about Rp360 million (about US$37,894).[1]

Efrizal, an Acehnese, had driven his own car from Aceh to Jakarta, boarding the Bakaheuni-Merak ferry in uniform; police said customs officers neglected to check the car because of the uniform.[1] In preliminary questioning he admitted it was his second delivery, saying he had brought 50 kg to Jakarta the previous month.[1]

A second marine was arrested that afternoon on information from Efrizal, and both men were held at the South Jakarta police station before transfer to Marine Corps headquarters, which took over the case because active soldiers were involved.[1] Two days later the corps conceded that at least four more marines could be involved, after its internal investigators confirmed their names.[1] Police traced the other names through five text messages on Efrizal’s phone, and tracked Pvt. Misbach, 31, to the Ciganjur intersection hours after the arrest after he texted that he wanted to buy 5 kg.[1]
