Michael T. Young, meanwhile, was allegedly drunk and charged with disorderly conduct. Police said the 35-year-old was yelling at other members of Occupy Boston, knocking over tents, and throwing objects around.

These arrests come after a confrontation with police earlier this week, when demonstrators tried to bring a sink into the encampment.
