More than $43m (£34m) has been seized from a flat in Nigeria’s main city, Lagos, the anti-corruption agency says.
Officials raided the flat after a tip-off about a “haggard-looking” woman in “dirty clothes” taking bags in and out of it, the agency added.
The money was believed to be from unlawful activity, but no arrests have as yet been made, the agency added.
This is the latest in a series of raids which uncovered bundles of cash in Nigeria, Africa’s biggest economy.
In March, the agency said it had found “crispy” banknotes worth $155,000 (£130,000) at the airport in northern Kaduna city.
