Two West Lothian prison guards were rushed to hospital after being 'poisoned' by an unknown substance on Thursday.
Emergency services rushed to HMP Addiewell as the prison was reportedly 'locked down' following a medical incident. A spokesperson for the jail confirmed guards responded to an incident where prisoners appeared to be under the influence of an 'unknown substance'.
As STV News reports, the guards became rapidly unwell and required medical attention. Images from outside the prison on Thursday afternoon showed multiple fire engines parked outside.
