Police said the suspects met the Croatian national on a dating application where they pretended to be a woman to extort him.
The police in Nigeria have arrested four Nigerians for allegedly blackmailing an unnamed Croatian man with his nude photographs.
The Force spokesperson, Muyiwa Adejobi, disclosed this in a statement on Thursday in Abuja.
Mr Adejobi, an assistant commissioner of police, said operatives from the National Cybercrime Center (NCC) of the Nigerian police arrested the suspects.
The spokesperson said the arrested suspects included Abodunrin Rasheed, Abodunrin Tunde, and Abodunrin Rokeeb.
He did not mention the name of the fourth suspect.
How it happened
Mr Adejobi said the suspects met the Croatian on a dating app where they pretended to be a woman to extort him.
He said the suspects continued chatting with the victim on Instagram and WhatsApp, where the Croatian, apparently thinking the suspects were a woman, agreed to an intimate relationship.
"The Croatian was deceived into sending nude pictures of himself through the dating app.
"The suspects subsequently conspired and pressured him (the Croatian) to pay ransom or have his pictures sent to his family and friends," he said.
Arrest of the suspects
Mr Adejobi said the suspects were arrested following receipt of a report through the police cybercrime centre's electronic reporting portal.
"The operatives of the NPF-NCCC conducted a due investigation, following the obtained information from the report, which led to the apprehension of the suspects," he said.
The force spokesperson said further investigations showed that the suspects had previously engaged in similar cybercriminal activities in the past where they allegedly defrauded and extorted numerous victims globally.
"The proceeds of these crimes were primarily received through gift cards like the iTunes gift cards, steam gift cards etc.," he stated.
"The suspects will be charged in court upon completion of the investigations."
Six iPhones, two Android mobile phones - Techno and Samsung - and a Lexus car were recovered from the suspects, according to the police.
The Inspector-General of Police, Kayode Egbetokun, has urged Nigerians to be careful about the activities of online fraudsters, Mr Adejobi said.
Mr Egbetokun also warned individuals and groups involved in similar cybercriminal activities to desist immediately.
"The Nigeria Police Force will not relent in its fight against all sorts of crime and criminality," he vowed.
