They include the former head of security for Ecuador’s congress, Colonel Rolando Tapia. They were found guilty of attacking President Rafael Correa during a protest last September.
The police were angry about plans to cut their bonuses and the president was forcibly detained. He had to be rescued by the military after being tear-gassed and held for several hours in a hospital.
The police chief resigned in the wake of the uprising, and was replaced the next day.
The six men will be sentenced later.
