US government officials told that the Nigerian man charged with trying to destroy a jetliner came to the attention of US intelligence in November when his father went to American embassy in Abuja, Nigeria, to express his concerns about his son.

A congressional official said Umar Farouk Abdulmutallab popped up in US intelligence reports about four weeks ago as having a connection to both al-Qaida and Yemen.

Another government official said Abdulmutallab’s father went to the embassy in Abuja with his concerns, but did not have any specific information that would put him on the “no-fly list” or on the list for additional security checks at the airport.

Neither was the information sufficient to revoke his visa to visit the United States. His visa had been granted June 2008 and was valid through June 2010. Both officials spoke on condition of anonymity because neither was authorised to speak to the media.
