According to The Hindustan Times, the men whose names include Sydney Obinna, Uzochekwu Clement, Alogsis Ezechinelu, Mike, Victor and Peter, were caught by a joint team of the State Special Operations Cell (SSOC) from Mohali and Patiala.
The news outlet reports that the men had been obtaining heroin smuggled from Pakistan, through Punjab and J&K borders.
They pump the heroin into an international network spread in Nigeria, Brazil, Pakistan, South Africa, Canada and the US, as well as some Indian states.
It is being alleged that the men were in contact with Pakistan-based heroin smugglers Abid Ali, Sajabad and Bhola.
A spokesperson reveals that the men will appear before a local court to obtain their police remand for them to be questioned thoroughly, establish linkages, and effect more arrests and seizures.
All six men were residing in a rented apartment in Uttam Nagar, New Delhi, where they were arrested.
