Leona Lewis, Justin Timberlake Song Leak Under Investigation

Simon Cowell's record label, SyCo, suspects computer hackers snagged 'Don't Let Me Down.'

Police are investigating the leak of a new [artist id="2490602"]Leona Lewis[/artist] song featuring [artist id="1231683"]Justin Timberlake[/artist] called "Don't Let Me Down," which is being considered for the British pop star's sophomore album, The Sun reported.

Simon Cowell's record label, SyCo, has partnered with the IFPI, which represents record companies worldwide, and the police to look into what they suspect was the work of computer hackers. According to The Sun, SyCo's computers were also allegedly hacked last month, and unfinished recordings by "X Factor" winner Alexandra Burke were leaked.

"IFPI is working with SyCo and law enforcement agencies in the U.S. and Europe to trace the individuals who stole the Leona Lewis/Justin Timberlake track," Jeremy Banks, head of IFPI's Internet Anti-Piracy Unit, said in a statement, according to Billboard.com. "The police investigation is ongoing. Such pre-release leaks, however they are sourced, are highly damaging to our members who invest considerable budgets in marketing and promoting music ahead of release."

SyCo thinks that the track was leaked by hackers and not by someone within the industry. In a statement to the BBC, a label rep said that the company's computers had come under a "sustained attack." The rep added, "We will certainly look to bring charges against those who are responsible."

Lewis, who won "X Factor" in 2006, released her chart-topping debut, Spirit, in 2007. Her second album is reportedly due out in November.
