Pop superstar Madonna thanked Israeli law enforcement on Thursday for helping to apprehend the Tel Aviv-based hacker who broke into her computer system and leaked unreleased music onto the Internet. The Israel Police special investigation unit Lahav 433 arrested a 38-year-old Tel Aviv resident on suspicion of hacking the computers of several musical artists, including Madonna, and stealing unreleased music to sell online.“I am profoundly grateful to the FBI, the Israeli Police investigators and anyone else who helped lead to the arrest of this hacker,” Madonna wrote on her Facebook page.“I deeply appreciate my fans who have provided us with pertinent information and continue to do so regarding leaks of my music. Like any citizen, I have the right to privacy. This invasion into my life – creatively, professionally, and personally – remains a deeply devastating and hurtful experience, as it must be for all artists who are victims of this type of crime.”In December, a slew of demos from Madonna’s album-in-progress, Rebel Heart, leaked online, forcing the superstar to release six tracks and move up the release date of the full album, which was due to come out in March. Madonna released the album for pre-order as an “early Christmas present” to her fans. It went to the top of the iTunes charts in 43 countries.
