Yesterday, several protestors participating in the Occupy Boston protests expanded from Dewey Square Park into the Rose Kennedy Greenway and adjacent green space between Congress St. and Pearl St. The Boston Police Department announced at 11 p.m. that the property was private and that protesters had to vacate it by midnight, or face trespassing charges.

Past that deadline, police arrived with riot gear and several paddy wagons and began arrests around 1:30 a.m. this morning. According to BPD Chief Daniel P. Linskey, about 100 people were arrested for unlawful assembly and trespass. They will be taken to local jails for fingerprinting and arraignment. Check out these pictures of the protests and arrests.
