Underground Illegals in Moscow

Today I read an article about an underground bomb shelter in Moscow that the police discovered full of illegal immigrants from Central Asia. In a 200 square meter shelter, there was around 110 people. That is not much space! The underground shelter had rooms, bathrooms, and even a prayer room. The people living down there were manufacturing blades and needles for sewing machines. The migrants will probably be deported and the owner of the sewing machine factory may be charged with organizing illegal migration.

It would be horrible to live in a bomb shelter! Being underground would not be fun! I wonder how they got down there. It must have been the factory owner, I guess. It is sad they are being deported, but living underground can't be great either.
