Story highlights The inmates escaped from the Arcahaie prison Saturday

A dozen have been captured

(CNN) A manhunt is underway after 174 inmates escaped from a prison in Haiti following a riot during which one guard was killed, authorities said.

The prison break occurred at a facility in Arcahaie on Saturday, said Inspector Garry Derosiers, the national police spokesman.

Of the more than 100 fugitives, a dozen have been captured, Derosiers said.

The uprising was led by "heavily armed individuals," according to a statement from the Prime Minister's office. It's unclear how the prisoners broke out or who the armed individuals were.
