National Unity Platform president Robert Kyagulanyi was arrested upon arrival at Entebbe airport at 10:20am.
He was met by security officials on the tarmac and transferred into a waiting convoy of cars.
Kyagulanyi had been on an international mobilisation tour for his party.
The Uganda Police confirm that Bobi Wine was “ successfully escorted by our security team from Entebbe to his home in Magere.”
However, a day ago police said that Kyagulanyi’s supporters would not be allowed to hold a procession welcoming him back into the country.
Several supporters were arrested on Wednesday after attempting to place placards in preparation for Kyagulanyi’s return.
“As we speak right now, I am officially not in Uganda because I did not go through immigration, they picked me illegally,” Bobi Wine said.
