Humza Yousaf has denied the SNP was "in cahoots" with Police Scotland over the timing of the arrest of its former chief executive.
Peter Murrell, the husband of Nicola Sturgeon, was quizzed by detectives yesterday before being released without charge last night.
At the same time, dozens of officers searched the SNP headquarters in Edinburgh as well as the house belonging to Sturgeon and Murrell in Glasgow.
