A predatory paedophile from the West Midlands whose "truly horrific" abduction of a 10-year-old boy sparked mass street protests has been jailed indefinitely for public protection.

Michael Jackson tied up and repeatedly threatened to kill the terrified victim, who was held prisoner in a cupboard during a three-hour ordeal after being dragged into a flat in Oldbury.

Ordering Jackson, 50, to serve at least seven years before being eligible to apply for parole, Judge Martin Walsh described the kidnapping as "the stuff of every parent's nightmare".

Wolverhampton Crown Court heard that Jackson gagged and trussed up the victim with duct tape and a rope, placed a craft knife near him, and warned him his father would be murdered.

The youngster, who was abducted in an isolated alleyway last November, only managed to escape from Jackson's flat in Bristnall Hall Road, Oldbury, after kicking open an airing cupboard door and raising the alarm at a window.

Passing sentence, Judge Walsh stressed that it was likely to be "very many years, if ever" before Jackson was judged to be safe to be freed from prison.

The paedophile, who was jailed in 1983 for the knife-point kidnap and indecent assault of a teenage girl, showed no emotion as the judge told him: "The facts of this case are truly horrific and are the stuff of every parent's nightmare.

"It is simply impossible to imagine the sheer terror experienced by that young child as a result of your actions."

Imposing the seven-year minimum term, the judge told Jackson: "I want to make it absolutely clear to you and the public that this does not mean that you will be released after serving this term.

"You will only be released once the Parole Board are satisfied that you no longer pose a significant risk of serious harm to children."
