Punjab Police have arrested a Nigerian drug smuggler with two kilograms of heroin worth Rs 1.8 crore, and tightened the noose around foreign nationals, especially from Africa, engaged in smuggling of narcotics, a senior police officer said today. Police described Frank Margin, 27, as a big fish, who was in touch with several Afghan nationals in Delhi and Afghanistan for supply of contraband to drug smugglers in the national capital and Punjab.

Currently residing in Delhi, Margin headed a gang of drug smugglers, who were all African nationals, said SSP Rupnagar, Swapan Sharma, adding that police were now trailing other gang members. Investigations revealed that Margin was in regular touch with more than 25 drug peddlers in various districts of Punjab, and had, in the July alone, sold nearly 3.5 kg of heroin and 60 gm of drug ice in the state.
