A rough (google) translation of the vaption to the video suggests that:
"After the end of this video, he tried to escape from us, we ran after him. He lied that he was going to the Smolensk region... We waited for ... the police... From the moment we drove up to [him], it took no more than 10 minutes... He [sat] in the Inspectors' car and [went] with them."
So sounds like it has a fairly happy ending -- although the would-be suicide will presumably need some support in the future too.
At any rate, an uplifting video.
