I would not necessarily read anything into that. I think it's pretty much automatic in Russian aerospace accident investigations for there to be a parallel criminal investigation. They did the same for an airplane crash in Sochi last month.Flyaway said:Some U.K. media are now referring to Russia launching a criminal investigation.
Krikalev suggested the investigation may be swift, promising results by Oct. 20. Though Russia has suspended Soyuz flights amid the investigation, launches have yet to be officially delayed or rescheduled — indicating Roscosmos is hopeful to quickly resolve the problem with minimal interruption to ISS operations and other Soyuz missions.

MOSCOW, October 20 - RIA News. The assemblers at Baikonur forcefully connected the side block of the Soyuz-FG rocket to the central unit, bent one of the mounting lugs and put the lubricant inwards so that it would come out when divided in flight, a rocket and space industry source familiar with the investigation told RIA Novosti.
According to him, on the thrust bearing - a special recess on the central unit of the second stage - there are two grooves on the sides, on the spherical bearing of the side unit of the first stage - two projections, and on the front part - a stem, which is clamped when placed in the thrust bearing.
“When it opens, a signal goes to the pyro lock opening the jet nozzle cover of the oxidizer tank to divert the side unit from the central unit. Assemblers during installation, when they connected the steps to the“ bag ”(four blocks of the first and second steps. - Ed.) the left ledge slightly bent, he didn’t immediately enter the groove - and he was driven out with force. When the step fell on him with the whole mass, the ledges, in fact, stood in a strut. interlocutor of the agency.
Thus, due to the bent protrusion, the ball bearing of the side unit could not easily get out of the thrust bearing and rammed the central unit during the flight, and then, at the exit, the stem sensor still worked and the valve opened, but by that time an emergency situation had occurred he explained.
According to the source, at the meeting of the emergency commission at the Progress Rocket and Space Center in Samara, the issue of production culture was raised, but experts said that such deviations from the technological documentation of the rocket assembly occur from time to time.
A source earlier said that the Roskosmos commission and the investigating authorities identified possible perpetrators of damage to one of the sensors of the Soyuz-FG launch vehicle and the state commission is inclined to the version of the "accidental departure from the documentation" by collectors at Baikonur.
Today, the state commission must sign the final results of the investigation and present them to the head of Roskosmos, Dmitry Rogozin, and the public will be informed about them early next week, RIA Novosti was told in a state corporation.
Russian engineers have a “really, really good idea” about what went wrong during a Soyuz launch to the International Space Station Oct. 11, forcing the ship’s two-man crew to carry out an emergency abort, NASA Administrator Jim Bridenstine said Tuesday. He added that he expects the Russians to resume piloted Soyuz flights in December.
