An open prison where buildings were burnt to the ground during a riot was "failing" in its fundamental role, inspectors have found.
Around 40 inmates took part in a New Year's Day mutiny at Ford Prison near Arundel, West Sussex, which saw buildings torched after an attempted clampdown on contraband alcohol.
Inspectors, who visited a month before the riot, had "serious concerns" about the prison, which they found was failing to prepare inmates for life back in the community. They also found security was undermined by poor relationships between staff and prisoners.
More than 40% of prisoners surveyed said it was easy to obtain illegal drugs and staffing shortages meant many random drug tests could not be carried out within the necessary timescales. Alcohol breath testing at the jail was also found to be "unsophisticated".
