The Investigation Committee of the Southern Federal District Prosecutor's Office announced earlier in the day it had resumed a probe into the May 9 explosion, in which Kadyrov died during a Victory Parade to mark WWII at a stadium in the Chechen capital.
"The decision... was declared groundless and premature, and was revoked," the Investigation Committee of the Russian Prosecutor General's office said in a statement.
The investigation into the case was resumed at the request of Chechen President Ramzan Kadyrov. Kadyrov said last week that his father was killed by former military commander Sulim Yamadayev, who was assassinated in Dubai on March 28.
"I have 70% proof that he was involved in the killing of my father, particularly as he tried twice to kill me, and wanted to poison a lake at my [Gudermes] residence on the day of my inauguration - I have witnesses," Kadyrov told reporters.
