Mityana Municipality Member of Parliament Francis Zaake has been arrested.
The legislator was picked by security operatives on Thursday night.
Authorities from criminal investigations told local media Zaake skipped a police bond which was granted to him last year.
"We have arrested Zaake. He jumped a police bond all this time. We are taking him to Arua Court, then Gulu."
Zaake is among the suspects who were arrested in Arua mid-August last year and charged with treason for pelting stones to the president's motorcade.
The MP caused a public uproar when images showing his deteriorating health condition surfaced on social media.
Police authorities accuse Zaake of unlawfully escaping from custody when his family secretly transferred him to another health facility.
Update: Zaake has been granted bail
