Judge releases Pakistani arrested at U.S. Embassy

A Pakistani man detained with suspicious chemical residues at the U.S. Embassy in Chile was charged with possessing explosives Saturday, then set free pending further investigation.

Mohammad Saif Ur Rehman Khan was ordered to stay in Chile and check in with authorities once a week. Prosecutors have three more months to develop their case, Judge Maria Carolina Herrera ruled.

Defense attorney Gabriel Carrion said the judge declined to charge Khan with associating with terrorists for lack of evidence.

Khan, who maintains his innocence, was called in to the embassy so that he could be told that his U.S. visa was revoked. A State Department spokesman in Washington said Khan had been added to a terrorism watch list after the U.S. government received information about him.
