An inquest has concluded that the deaths of three friends who were stabbed in Reading four years ago were “probably avoidable”.

The judge coroner said the failings of multiple agencies contributed to the killings by Khairi Saadallah – a Libyan refugee released from prison 15 days earlier who should have been treated as extremist and “very dangerous”.

The parents of one of the victims told Channel 4 News they hope today’s findings will prevent other families going through the same needless heartbreak.
