Had to read up a bit, but either way i seem to have mixed something up. I did not know the French tear gas grenades also had TNT in them. But I read about such flashbang/teargas mixups before their introduction in 2011. The non french sources are a bit muddy, but Vital Michalon seems to have died at Superphénix due to a sock grenade damaging his lungs?

But nevertheless it seems i mixed up France with Switzerland here. Though I cant find the original source I had in mind, Guy Smallman had his leg severely injured in Geneva during the 2003 G8 summit by a shock grenade.

Thanks for the heads up!
