No fewer than 11 suspects have been arrested by personnel of the National Drug Law Enforcement Agency, NDLEA in operations that led to the seizure of almost four tons of skunk in Kaduna, Kano and Lagos states. It was learnt that the agency also thwarted attempts by elements of organised criminal groups to use various disingenuous modes of concealment to import consignments of illicit substances into Nigeria and export the same to the United Kingdom and the United Arab Emirates through the Murtala Muhammed International Airport, MMIA, Ikeja and Tincan seaport in Lagos.
