SAN FRANCISCO (KRON) -- San Francisco police continue to monitor an abandoned building at Turk and Gough Streets where several hundred demonstrators remain inside.

Police blocked Turk Street for several hours Tuesday evening while the protestors broke through a chain link fence and set themselves up inside the building owned by the Roman Catholic Diocese of San Francisco.  Supporters of the occupiers say they are creating a commune inside the building.

Paramedics offered to treat a man who was hit in the head by a flying brick coming from the roof of the building.  He declined treatment.

Police arrested 34-year old Jesse Nesbitt and charged him with two felonies in connection with the thrown debris.

By late evening police had re-opened Turk Street while officers continued to monitor the situation.

Diocese officials tell KRON 4's Alejandra Cerball they're uncertain as to why their abandoned building was targeted by the protesters.
