Tim Lambesis, the singer of Grammy-nominated US heavy metal band As I Lay Dying, has been arrested after police uncovered his plan to have his wife killed by a private detective. The rock star, 32, had made the necessary steps to have his wife Meggan killed though authorities were passed information and made the arrest before it was too late, reports BBC News.

"The information came to us late last week. We acted quickly on it. I believe that we averted a great tragedy," said a police spokesperson. The rock star was arrested "without incident" in San Diego on May 7.

The singer's wife had filed for divorce in September last year, according to San Diego Superior Court documents. The couple adopted three children from Ethiopia together in recent years before separating. The details as to how Lambesis planned to have his wife killed are currently unclear.

As I Lay Dying, who formed in 2000, have sold more than a million albums through the Metal Blade record label. Their 2007 album An Ocean Between Us reached No.8 in the US album chart and featured the Grammy-nominated track Nothing Left. The band are set to tour the US with several other metal acts later this month, though it's unclear whether Lambesis will make the trip. Fans should look out for updates on the group's official website.
