A 38-year-old Nigerian was arrested here Thursday in connection with the seizure of a narcotic substance, the Narcotics Control Bureau said.
Based on a tip-off, NCB officials Wednesday seized 200 gm of methamphetamine, a stimulant drug, concealed in small machine parts in a parcel, a release from the bureau said.
"The parcel was booked by the arrested person to Doha in Qatar in September. However, it was not delivered in Doha and was returned to Chennai," it said.
The release did not disclose the Nigerian's identity and where the seizure was made.
The drug was sourced from another Nigerian living in Delhi, it added.
