An American detained in Pakistan for shooting two armed men was working as an undercover for the Central Intelligence Agency or CIA at the time when he was taken into custody.

This revelation is expected to further hold back the efforts of the U.S. government to free the individual, and aggravate the relationship between both countries that are only partnered by a delicate alliance to fight against terrorism.

According to unnamed current and former U.S. officials, Raymond Allen Davis had been secretly working for CIA as a security contractor intended for the U.S. consul’s office located in Lahore. He is a former soldier in the Special Forces command and left the military in 2003.

Davis shot the men in a city located east of Lahore as they moved towards him on a motorcycle. He said it looked like they were attempting an armed robbery. A Pakistani bystander died when he was hit by a car speeding up to help Davis. Davis was alleged carrying papers with several identifications, a pocket telescope and a Glock handgun.

The disclosure that David was a former employee of the CIA appeared in the midst of a chaotic argument over his immunity guided under the international rules used to protect civil servants overseas.

Protests in Pakistan occurred when Davis’ affiliation with the CIA was published in the Guardian newspaper in London. The government of the United States has emphasized that Davis had diplomatic immunity. Thus, he should have been freed immediately.

From the time that Pakistani authorities arrested the former Special Forces soldier in January 27, officials from United States said that the situation has gradually progressed into a crisis. It threatens the ability of the CIA to stop a frightening war against militants and al-Qaida.

Some Congress members have even warned the will try to stop the billion dollars worth of funding to Pakistan if Davis is not yet released.
