Indian authorities Tuesday seized more than $2 million in cash from a Nigerian diplomat on his way out of the country.

Investigators in New Delhi released the Nigerian diplomat, G.A. Ojedokun, Tuesday. He was detained at an airport in the capital on Monday after security screeners found $2.3 million in cash in his baggage.

Authorities who interrogated the diplomat refused to allow him to board his flight to Lagos, Nigeria.

They say he failed to adequately explain why he was traveling with so much cash.

Officials released the man Tuesday after he demanded diplomatic immunity, but they refused to return the cash. They add they have informed Nigerian authorities about the incident.

The diplomat has been stationed in New Delhi since early this year.

There was no immediate comment from the Nigerian government.
