The man identified as 'Raja' is a resident of Veraval in Somnath district of north-east coastal Gujarat and he had allegedly leased the dhow-- Laxmi Narayan-- from a small-time businessman of the same locality, official sources said here.
Following reports in the international media, central security agencies began a suo-motu investigation comprising intelligence and anti-narcotics sleuths into the case.
The incident came to light on April 24 when reports said a patrol of Combined Maritime Forces (CMF) led by Australian authorities intercepted the large Indian dhow near the Mombasa coast in Kenya recovering over 1,000 kg of Heroin.
The sources said investigating agencies, at present, are questioning at least eight suspects in the case after it came to light that the owner of the dhow complained to Veraval police that the person, whom he leased the boat that was detained in international waters, is absconding and has cheated him.
Sources said Australian authorities have recently sent a communication to Indian agencies stating the said interception was indeed made and three Asians-- two Pakistanis and an Indian-- were questioned by them but they were let off.
