Indian Police arrests six Nigerians in spam scam case, seized 14 laptops, seven memory sticks and 23 mobile phones along with fake documents and cash.
The arrests came after security firm Kaspersky Labs reported more spam originated from India than any other country in the world.
According to the Kaspersky report, 14.8% of all spam email sent in the three months prior to the end of September had originated in India.
Police said the six men, all Nigerian, would be remanded in custody until 12 January.
Mumbai-based internet security specialist Vijay Mukhi said poor enforcement of laws meant spammers could act with impunity.
"We have an Information Technology Act that was introduced in 2000. But we don't have any convictions under it and it's silent on spam," Vijay Mukhi said.
"If I'm a spammer, I would rather spam from India to India and the rest of world because nothing will happen to me."
