The Economic and Financial Crimes Commission (EFCC) says it has arrested 32 people on suspicion of cyber-fraud.
In a message posted on its Twitter account, the EFCC said it arrested the men in a raid on house number 12, street 2, Goodnews housing complex, Lagos on Monday morning.
Following a string of intelligence-gathering operations, she was able to make a successful operation.
The men have long been accused of defrauding people before they were arrested.
The commission said it would take them to court as soon as it completed its investigation.
