A group of Occupy protesters -- the Guitarmy -- who marched from Philadelphia to NYC converged with local demonstrators at Zuccotti Park this afternoon, where two activists were arrested and a woman collapsed during a chaotic confrontation with the NYPD.

According to emails this evening, the woman on the ground is Mary, (No last name given, sorry.) she's an activist from Washington State who sometimes marches dressed as the Statue of Liberty. Mary participated in the week-long 99-mile Guitarmy march from Philadelphia, which reached NYC today. Conflicting reports on how she wound up on the ground, some say she was knocked down by police, but others say suffered heat stroke and passed out. Word now is that she was treated at the scene, released and is doing fine.

This next video is the arrest of one of the drummers who was one of many musicians at Zuccotti Park:

Apparently, all the chaos started as the protesters were about to enjoy a pasta dinner and security started carrying off the food, and I imagine all those marchers were pretty hungry about then, too.

Here's a photo of livestreamer Jeff's arrest (Jeff sometimes assists Tim Pool, @Timcast)

Tim Pool finished livestreaming for the night with one last update, here, where the tensions seem to have diminished with around 100 protesters still in Zuccotti Park and a huge police presence remaining. No word on the reason for the arrests earlier. Hopefully everyone will remain calm through the night. I'll check on updates in the a.m.
