On March 24, 2005, Kulov was released during the Kyrgyz revolution (the Tulip Revolution) and appointed as co-ordinator of law enforcement and security services (effectively, the Kyrgyz head of security) by acting president and prime minister Kurmanbek Bakiyev.
On 6 April a special working group of the Kyrgyz Supreme Court was formed to review Kulov's earlier prosecution and convictions, and by 11 April he had been cleared of all charges.
