The Pentagon says there may be more U.S. military members under investigation for alleged inappropriate behavior in Colombia than the five announced over the weekend.
Pentagon press secretary George Little said Monday that he could not provide a specific number, but that military members who are being investigated were assigned to support the U.S. Secret Service in preparation for President Barack Obama's visit to Cartagena. He said they were not directly involved in presidential security.
The Secret Service sent 11 of its agents home from Colombia amid allegations that they had hired prostitutes at a Cartagena hotel.
The U.S. Southern Command had announced on Saturday that five service members assigned to the presidential mission in Colombia had violated curfew and may have been involved in "inappropriate conduct."
