Vijay Kumar, 40, an Indian national has been arrested at Houston airport for carrying jehadi literature and brass knuckles. He was arrested on Friday at the George Bush Intercontinental Airport after security officials searched his luggage when they noticed him behaving strangely. Kumar had said that he was a documentary filmmaker from Mumbai.

The security officers found books and diagrams on espionage, information on US military weaponry, publications mentioning 'jehad' and 'infidels', brass knuckles and at least $8,000 in US bills, a US news report said.

Kumar told investigators that he was in Houston for an 'Islamic seminar'. He was being held on a $50,000 bond. Kumar was in Houston to lecture a Hindu organization about Islamic fundamentalism and the books in his luggage were educational tools, authorities and his lawyer said.

Kumar’s attorney said he has surrendered his passport to the officials. He does not want a criminal record to interfere next time he visits the US.

Scheiner said, 'I think that everybody realized that he is not a threat. He's a peaceful man,’ 'He was here to visit the Hindu Congress of America, to deliver a lecture. It was about an interfaith discussion between Hindus and Muslims about the harms of terrorism.'
