Police say more than 70 people were taken into custody following a rally at the park where the Occupy movement was born.
Hundreds of protesters had returned to Zuccotti Park near Wall Street on Saturday to mark the six months that have passed since the movement began. They locked arms and sat down after police announced on a bullhorn at around 11:30 p.m. that the park was closed.

Officers poured into the park, forcing out most of the crowd and surrounding a small group that stayed behind.

Police formed a human ring around the park to keep protesters out.

Authorities say 73 people were detained. It was unclear how many were still in custody Sunday afternoon.

For hours, the demonstrators had been chanting and holding impromptu meetings in the park.
