(Bloomberg) -- Ugandan opposition leader Bobi Wine, who was freed after 11 days under house arrest, demanded that the authorities also release hundreds of his jailed supporters.

Security forces withdrew from Wine’s home on the outskirts of the capital, Kampala, after a High Court judge ruled Monday that his confinement was unlawful. Wine, a pop star-turned politician whose real name is Robert Kyagulanyi, is disputing the outcome of the Jan. 14 election, in which President Yoweri Museveni secured a sixth straight term.

The lead-up to the vote was marred by violence, with at least 54 people dying after protests that erupted because of Wine’s arrest in November. Wine said more than 400 supporters, including members of his campaign team were arrested.

“We continue to demand for their freedom,” Wine told lawmakers in a briefing broadcast on Facebook. “I was personally put under illegal detention in my own house because General Museveni did not win.”

Wine’s National Unity Platform party is weighing challenging the results in court.

Wine, 38, who presented himself as a youthful alternative to the 76-year old Museveni, secured 34.8% of the votes cast. Museveni got 58.6%, official results show. The electoral commission and Museveni denied the vote was rigged and called for the outcome to be respected.
