Zaake had joined fellow MPs, Robert Kyagulanyi (Bobi Wine), Paul Mwiru and Gerald Karuhanga to campaign for Kassiano Wadri, the eventual winner of the Arua Municipality by election held in August.
It is alleged opposition supporters obstructed the president's motorcade and pelted stones that smashed the windscreen of one of the vehicles in the convoy. More than thirty people were arrested in the aftermath and charged with treason.
Zaake, who did not appear in court alongside the rest, was accused of escaping from police custody. Later, shocking pictures of him were circulated on social media, showing a swollen face and badly damaged fingers. He later resurfaced in Lubaga hospital under unclear circumstances.
Lying helpless in the surgical ward at Lubaga hospital, Zaake remained unconscious for days supported by a nebulizer and feeding tubes. He complained of multiple pains around the head, the neck, lower back, and the lower limbs.
A scan later indicated that Zaake had a vertebral complication requiring special treatment. His initial attempts to fly out of Uganda for treatment were thwarted, when Zaake and Bobi Wine were arrested from Entebbe airport and forcefully transferred to the government-owned Kiruddu hospital by police. Following internal and external pressure, He and Bobi Wine were later cleared to travel abroad for treatment.
Zaake announced that he will be returning to the country after completing his treatment at Manipal hospital in India.
"I still have mild pain in my neck, spine and chest and I also lack balance while walking. This is the price that those with dissenting views other than that of the state pay. Our struggle is non-violent and shall maintain that until people realize the strength of their power," Zaake says.
