Brazilian police say they have arrested a Lebanese woman wanted for questioning over the death of former Lebanese Prime Minister Rafik Hariri.
The investigation into Mr Hariri's death is still going on
Rana Abdel Rahim Koleilat, 39, was arrested on Sunday in the city of Sao Paulo after an anonymous tip, the police said in a statement.
Mr Hariri was killed in a massive car bomb in Beirut in February 2005.
A UN investigation into his death is ongoing and has implicated Syrian and Lebanese officials.
Police Inspector Nicanor Nogueira Branco said in a statement that Ms Koleilat had been arrested at a hotel in the city.
She was arrested for attempted bribery after offering officials up to 200,000 Brazilian reals (US$94,000, £54,000) to let her go, police said.
She was in possession of a British passport identifying her as Rana Klailat of Northern Ireland, police said.
Joseph Sayah, the Lebanese consul-general in Sao Paulo, said the Independent International Investigation Commission, set up to investigate Mr Hariri's death, wanted to question Ms Koleilat.
He said she was also wanted in connection with alleged bank fraud in Lebanon, the Associated Press news agency reported.
Twenty people were killed in the February 2005 attack in which Mr Hariri died.
