KAMPALA, Uganda (AP) — Ugandan pop star and opposition figure Bobi Wine says he is concerned about his safety four days after returning from the United States, where he sought medical care for injuries sustained during alleged state torture.

Bobi Wine, whose real name is Kyagulanyi Ssentamu, told reporters Monday that "I don't feel safe at all ... My family lives in fear."

Ssentamu, a lawmaker since last year, says he's fighting for freedom from oppression and wants President Yoweri Museveni, in power since 1986, to retire.

He was arrested and charged with treason over his alleged role in an Aug. 13 incident in which the president's convoy was pelted with stones.

The government denies allegations Ssentamu was tortured.

Ssentamu said he's awaiting the results of toxicology tests carried out in the U.S.
