Umar Farouk Abdulmutallab, a Nigerian who allegedly tried to blow up a US plane, had "sneaked" into Nigeria on December 24, a day ahead of the failed terror bid, country's information minister has said. "The man in question had lived outside the country for a while. He sneaked into Nigeria on December 24, 2009 and left the same day," Dora Akunyili, Nigerian information minister said.
