He has 62% of the vote, while Mr Beisgye has 33%, according to provisional results released by the electoral commission. This is the third time in the space of a week that Mr Besigye has been detained.
The police have not said why he was arrested or where he is being held.
The US embassy in Uganda condemned the crackdown in a post on its Twitter account:
After Mr Besigye was briefly detained on Thursday, the US State Department said the arrest called into question "Uganda's commitment to a transparent and free election process".
It also criticised a temporary shutdown of social media, chat apps and mobile money services.
President Museveni said the decision had been taken for security reasons, and to prevent people from "telling lies".

Social media was also blocked on Thursday in Uganda to prevent people from spreading "lies", Mr Museveni said. Commonwealth election observer mission head Olusegun Obasanjo condemned the failure of voting stations to open on time.
Critics said the decision showed that Mr Museveni, one of Africa's longest-serving rulers, was becoming increasingly tolerant. "Delays of three, four, five and even six hours, especially in Kampala, are absolutely inexcusable and will not inspire trust and confidence in the system and the process," he said.
A candidate needs to secure more than 50% of the vote to avoid a run-off with the second-ranked contender.
Ugandans also voted in parliamentary and local elections.
Final results are expected by Saturday.
