It’s not a swastika. It’s a faked picture with a mass market cheap bracelet with a Scandinavian rope motif that (if blurred) looks like a swastika.
The officer in question has been wearing the same bracelet for at least a year and OTHER photos of it, enlarged, confirm it isn’t a swastika.
A TV investigation went thoroughly into it thru multiple appearances, then located the bracelet online.
There are several other investigations, all proving that this is fake news.
Given the same images are copied, pasted and spammed out by the St Petersburg troll farm, it’s safe to say they manufactured the story and lots of dupes are still falling for it.
Addendum: this isn’t to say there are no Nazis in Ukraine, because clearly there are. Thousands.
Some fight for Russia, some fight for Ukraine,
And an awful lot of them (like the kids in pictures doing nazi salutes) are noncombatants.
There’s really no need for Russian propagandists to besmirch a non Nazi with a false accusation. There’s enough real Nazis on the battlefield to keep ‘em busy.
