Olosky Lolanko was held at the Tribhuvan International Airport (TIA) yesterday, the Narcotics Control Bureau (NCB) of Nepal Police said.
Lolanko was taken into custody when he was about to board a flight to Mumbai from where he would have flown further to Ukraine, the Kathmandu Post quoted the NCB as saying.
He had concealed the contraband inside a bottle of 'chyawanprash', a herbal supplement, and some portion of it in his sports shoes which were kept in a suitcase, it added.
