“He has been confined. It is house detention and we do not know how long this will last.
“Security forces have surrounded his home,’’ lawyer Meldad Sseggona told dpa.
Wine, whose real name is Robert Kyagulanyi, was temporarily detained on Monday but then released without charge after he was prevented from staging a music concert.
The 37-year-old – who has said he plans to run for president in elections in 2021 – has since called for mass protests.
“Police and the military have been deployed at my residence since yesterday, after the violent arrest. My home is under siege.
“They have surrounded my fence and installed barricades on all roads leading to my home.
“It is today when I attempted to move out of my home that the police told me that I am under house arrest.
“I was headed to deliver a notification about our planned peaceful demonstrations against police brutality, injustice and misuse of authority,’’ he added.
Wine, who is a vocal presence on social media and has a large youth following, has become a thorn in the side of Ugandan President Yoweri Museveni, who has ruled the country for over 30 years.
