Author of critical Obama book arrested in Kenya

Kenyan immigration authorities have arrested the US author of a critical book about presidential candidate Barack Obama before a launch in Nairobi.

Jerome Corsi, who penned The Obama Nation , arrived at a Nairobi hotel to present his book in Kenya, but was quickly whisked away by immigration officials, witnesses said.

"He was walking in and then some immigration officers who were following him snatched him," a hotel worker said. "It happened so fast, they just vanished with him."

Mr Obama is revered in Kenya for his paternal roots there and as a flagbearer for Africa on the international stage.

Mr Corsi's book, which critics say is meant to hurt Mr Obama's poll prospects next month, questions whether he could still be using drugs and insinuates the Democratic candidate is Muslim.

Kenyan TV station KTN said Mr Corsi may be deported due to lack of a work permit.
