WASHINGTON -- Police say two Burundian teens who disappeared from an international robotics competition in Washington have been found safe.

A Metropolitan Police statement Tuesday said Don Ingabire and Audrey Mwamikazi, who were seen crossing into Canada, "have been located safely." A police spokesman declined to comment on where they were found, citing department policy for missing person cases.

Police are still investigating the whereabouts of the other four teens on the team who disappeared. Authorities have said there are no indications of foul play.

Event organizers believe the teens may have planned their disappearance. Members of the Burundi-American community say they have little doubt the teens are planning to seek asylum, either in the U.S. or in Canada.
