Police in Amsterdam arrested more than 100 West Africans as part of a 7-month long investigation into Internet fraud, an AFP report said.
The AFP report quoted police spokeswoman Sita Koenders as saying that 111 people were arrested for being in the Netherlands illegally and 'now we must investigate in what way they are implicated in Internet fraud.'
Eight of those arrested were carrying false papers and they have been prosecuted, the AFP report said.
The others were detained and then released unless there were any extra charges against them, the police said in a statement.
In October, Dutch police launched Operation Apollo to fight Internet fraud scams operated by West Africans and notably Nigerians, the report said.
The scams involve sending emails all over the world promising recipients quick financial gains from a make-believe inheritance or fictitious lottery wins in exchange for 'processing fees' of several thousand dollars, the report said.
Dutch police believe over 2,000 Internet fraudsters are active in the country, the report further said.
