Four minor girls were rescued on Wednesday from Kamkhaya railway station when they were being taken to Bihar by suspected traffickers, a senior police officer said.
One person, identified as Bokuli Bordoloi, was arrested in this connection, he said.
Acting on a tip-off, Morigaon district police launched an operation and managed to rescue the four girls from Awadh- Assam Express, SP Swapnanil Deka said.
Bordoloi had promised these girls jobs at a dance centre in Bihar's Muzzafarpur town, he said.
During questioning, he named three of his associates, Deka said, adding that a search operation is under way to nab them.
