A "very dangerous" British prisoner is among five inmates who have escaped from a high-security prison in Portugal.

Mark Cameron Roscaleer, 39, had been serving a nine-year sentence for kidnap and robbery at the Vale de Judeus jail, about 43 miles (70km) north of Lisbon.

The five men, aged between 33 and 61, fled on Sunday morning and received "external help" from accomplices who provided a ladder which "allowed the inmates to scale the wall", according to the Portuguese prison service (DGRSP).

Frederico Morais, president of the National Union of Prison Guards (SNCGP), described Roscaleer as "very dangerous" and advised people that if they see him or the other inmates, they should not to approach them.

He also provided details about the escape: "They managed to jump a net because there are no guards to watch the perimeter... put the ladder against the wall and, from there, with a handmade rope, they climbed over the wall".
