Ugandan police say they have arrested some people over the kidnapping last week of an American tourist who has since been freed.

Police did not specify how many people were arrested but said they were “actively investigating” the kidnapping, which took place on April 2 in a national park.

The victims — Kim Endicott of Costa Mesa, Calif., and local driver Jean-Paul Mirenge — were freed Sunday.

Police said the hunt for the kidnappers, including “raids and extensive searches,” was taking place in southwestern Uganda.

President Trump has urged Ugandan authorities to find the perpetrators.

The kidnappers had demanded a $500,000 ransom after abducting the two at gunpoint.

Ugandan officials say no ransom was paid, but a tourism operator said money was paid to secure Endicott’s release.
