More than 300 people associated with the Occupy Wall Street movement gathered in Zuccotti Park on Saturday and, in a return to scenes from earlier in the year, held a general assembly meeting, chanted the now familiar slogan “We are the 99 percent” and experienced a bit of friction with security guards.

At about 7 p.m. on New Year’s Eve, about 100 people started flowing into the park, according to witnesses, and someone erected what was described as a small tent built for a child. Two young girls, who were at the park with their mother, began playing inside.
