KATHMANDU, July 31: Controversial businessman Rakesh Kumar Adukia, wanted by the Department of Revenue Investigation (DRI), is suspected to have left the country. It is assumed that the Adukia father-son duo who was involved in the smuggling of around 100 kilos of gold has left the country. Merely a week after the successful recovery of the smuggled gold, the DRI’s raid on his house proved futile, as the team returned only with a handful of documents. The DRI team that raided Adukia's house in Kamalpokhari hasn’t yet paid attention to his factory in Maligaon.
