Police have made four more arrests in the major drug operation called Project Deplete, a long-term investigation by the Manitoba Integrated Organized Crime Task Force. More than 80 officers made arrests and seized more than a million dollars worth of drugs on Friday. A total of 13 people were charged and seven people were arrested at that time, said police. On Monday, they announced four more arrests: Kareem Martin, 31, Dane Sawatzky, 27, Mark Beitz, 31, and Dalton Miller, 21. On Tuesday, RCMP said Elmer John Deato, 26, had also been taken into custody. A warrant for arrest remains in effect for David Thomas, 29, of Winnipeg, Manitoba for weapons trafficking and other offences. Those taken into custody Friday include: William Lauren Bowden, Joshua James Lyons, Chi Hong Do, Christopher Lea Murrell, Pardeep Kapoor, Joshua Robert Charney, all of Winnipeg and Ramsey Yaggey of Edmonton. "We've had a lot of success in the last while with the Hell's Angels, taking them off the street, the Zig Zag Crew and others," said Winnipeg Police Chief Keith McCaskill on Friday. "When that happens quite often there is a void left open and there is people jockeying for position." On Friday officers seized: 6,912 grams of cocaine, 465 grams of crack cocaine, 272 grams of methamphetamine, 9,811 ecstasy tablets, 1,063 grams of MDMA, 501 oxycodone tablets and 891 grams of marihuana. A number of the accused made an appearance in court Monday, including Hell's Angel member Billy Bowden, who was charged with three counts of trafficking cocaine and two counts of possessing the proceeds of a crime. Many of the accused have been remanded to March 14. Some of their lawyers expressed their intention to seek bail in the meantime. Project Deplete began in August and focuses on high level independent drug traffickers in Winnipeg and around the province. Officers from the Winnipeg Police Service, RCMP and Brandon Police Service participated in Friday's bust.
