Tamim was found dead in her Dubai apartment on 28 July
A man has been arrested in connection with the death of Lebanese pop star Suzanne Tamim, police in the Gulf emirate of Dubai have said.
The 30-year-old singer was found dead in her flat last month. Media reports suggested she had been stabbed repeatedly and decapitated.
The suspect, a 39-year-old man, was arrested a few days ago in another Arab country, with help from Interpol.
Dubai's acting chief of police, Mattar al-Mazeina, would not identify him.
Speaking to reporters, Mr Mazeina said the man had posed as an estate agent to gain access to the singer's flat.
He added that the suspect had left the United Arab Emirates 90 minutes after the murder, and said police had tracked him down with the help of evidence collected at the scene.
Tamim rose to fame after appearing on a TV talent show in Lebanon in 1996, but her career was marred by stories about a troubled private life.
She was reported to have fled Lebanon to Egypt some years ago after a number of bitter legal battles with her estranged second husband, music producer Adel Maatouk.
She gave up her career and disappeared from public view in Cairo in 2007 and was thought to be living in Dubai's exclusive Jumeira district.
