London (CNN) -- WikiLeaks founder Julian Assange was arrested Tuesday on a Swedish warrant, London's Metropolitan Police said.Assange turned himself in at a London police station at 9:30 a.m. and will appear at the City of Westminster Magistrate's Court at 2 p.m., police said.
Swedish authorities had issued the warrant for Assange so they can talk to him about sex-crime allegations unrelated to WikiLeaks' recent disclosure of secret U.S. documents.
Assange has not been charged.
At court, Assange will be able to respond to the arrest warrant, and the court will then have roughly 21 days to decide whether to extradite him, said Mark Ellis, executive director of the International Bar Association.
