Peter availed himself of savage tortures while investigating the incident. Many suspects were whipped to death with the knout, an extremely stout leather whip composed of numerous twisted strands. Many were stretched until their limbs broke; sophisticated iron thumbscrews were applied to the fingers and toes of some prisoners; while other had their backs slowly roasted or had their flanks and bare feet slowly torn apart with red-hot iron pincers. Peter thus induced suspect after suspect to name accomplices in a virtually unending cavalcade of forced, and likely often fake, confessions. As a result of a major investigation, 57 Streltsy were executed and the rest sent into exile. Upon his hurried return from London on 25 August 1698, Peter I ordered another investigation. Between September 1698 and February 1699, 1,182 Streltsy were executed and 601 were whipped, branded with iron, or sent into exile. The investigation and executions continued up until 1707. The Moscow regiments, which had not participated in the uprising, were later disbanded. Streltsy and their family members were removed from Moscow.
