BOGOTA, Colombia (AP) _ Police on Thursday freed a U.S. citizen who had been abducted hours earlier in the southern city of Cali and captured two men allegedly involved in the kidnapping, a police spokesman said.

Gerald Robinson, hometown unknown, was freed unharmed in Cali, said a spokesman for the national police.

The spokesman, reached by the Associated Press by telephone, refused to give his name. He said police captured two suspects, William Garcia and Luis Mazo, but had yet to establish why they wanted to kidnap Robinson.

The spokesman said he had no further information about the victim or the abduction, which occurred late Wednesday.

Lauren Hale, a spokeswoman for the U.S. Embassy in Bogota, said she was looking into the matter but could not yet confirm or deny the kidnapping.
