A jury in Puerto Rico has convicted five people of fraudulently obtaining medical licenses to work as doctors in the U.S. territory.

The five were among dozens of people arrested in August 2007 as part of a federal investigation into allegations that members of the island's Medical Examiners Board took bribes to change failing exam scores. A sixth defendant was acquitted.

Jurors convicted the other five of fraud in Thursday's verdict. Two also were convicted of identity theft.

The U.S. attorney's office in Puerto Rico said Friday that there is no evidence any patients were harmed in this case.
