Stingy little friend in the bathroom

I found this scorpion today in the bathroom, under bucket on the moist floor, in the micro-plant that I am prepearing, in southern Republic of Macedonia.
I can\'t identify the species correctly, but most probably it is Euscorpius italicus or more poisonous Mesobuthus gibbosus? It measured about 5 cm from the head to tail sting (telson).

What happened with the scorpio? I relеased it in the moist grass just outside the micro-plant, on a day light (noon), I think it will survive.
