Public warned not to approach men believed to have escaped high-security facility with help from outside

A British inmate is among five prisoners on the run after breaking out of a high-security prison in Portugal, local authorities have said.

The man, named locally as Mark Roscaleer, and his fellow fugitives were said to have escaped from the Vale de Judeus facility on Saturday with help from people on the outside. He is serving a nine-year prison sentence for kidnap and robbery, according to Portuguese media.
