The public inquiry into man who died in police custody is seeking a ban on prosecuting officers using the evidence they give at its hearings.
The inquiry is being held into the 2015 death of Sheku Bayoh after he was restrained by officers responding to a call in Kirkcaldy, Fife.
Its chairman Lord Bracadale issued his ruling on Tuesday confirming he will request undertakings from the Solicitor General and Deputy Chief Constable of Police Scotland.
