A notorious Tanzanian drug-trafficking kingpin has been arrested in Zambia during a raid, the Zambian Drug Enforcement Commission (DEC) has announced. Ahmed Muharram was among several suspects detained in Zambia's capital, Lusaka, along with large quantities of marijuana and cough syrup containing codeine in several drug busts on Tuesday, the authorities said. The suspect is a known transnational drug trafficker, the DEC said, adding that the 40-year-old had long been on the anti-drug agency's watch-list. The arrest of Muharram, who has not yet commented, was made possible thanks to a series of intelligence-led operations, the agency said. Under Zambian law, marijuana is classed as a dangerous drug and is illegal to possess. The trafficking, possession, and use of illegal drugs such as cannabis is punishable by a fine or a prison sentence. The southern Africa country struggles with drug abuse and trafficking, especially cannabis and heroin. During Tuesday's operations, the DEC said it had seized 221.2kg of cannabis hidden in a lorry in Lusaka's Lilayi area. The search was extended to Muharram's residence in Lilayi, where officers discovered an additional 1,159.6kg of high-grade cannabis, bringing the total seizure to 1,380.8kg, the agency added. A Zambian national who was also arrested is believed to be an accomplice in the organised drug-trafficking scheme. The DEC said their operations also saw the arrests of multiple individuals involved in various drug trafficking activities, emphasizing their commitment to ensure that Zambia is not a corridor or destination for drug trafficking.
