Calm at Occupy LA site after arrests

Last Updated 1:56 p.m. ET

LOS ANGELES - Deadlines for Wall Street protesters to leave their encampments came and went in two cities with no arrests in Philadelphia but four people taken into custody in Los Angeles several hours after the midnight deadline passed.

Los Angeles Police Chief Charlie Beck said it remained unclear when the nearly two-month-old Occupy LA camp would be cleared. About half of the 485 tents had been taken down as of Sunday night, leaving patches of the 1.7-acre park around City Hall barren of grass and strewn with garbage.

"There is no concrete deadline," Beck told reporters Monday morning after hundreds of officers withdrew without moving in on the camp. The chief said he wanted to make sure the removal will be done when it was safe for protesters and officers and "with as little drama as possible."

Protesters chanted, "We won, we won" as riot-clad officers left the scene.

"I'm pretty much speechless," said Clark Davis, media coordinator for Occupy LA.

Police turned back after hundreds of Occupy LA supporters showed up at the camp Sunday night as the midnight deadline for evacuation neared. As the night drew on, many demonstrators left.

Protester Julie Levine said she was surprised that police did not move in as the numbers dwindled. "We were fearful," she said. "But we held our numbers and police were on their best behavior."

A celebratory atmosphere filled the night with protesters milling about the park and streets by City Hall in seeming good spirits. A group on bicycles circled the block, one of them in a cow suit. Organizers led chants with a bull horn.

Officers reopened the streets at around 6:30 a.m.

"Let's go get breakfast," said Commander Andrew Smith as he removed his helmet.

CBS Station KCBS reports the scene was calm at 6:30 a.m. PT, with traffic moving at 1st and Main Streets, where protesters are gathered.

The protest was largely peaceful but there were some skirmishes. Four people were arrested for failure to disperse and a few protesters tossed bamboo sticks and water bottles at officers, Smith said. No injuries were reported.

A hearing in federal is scheduled for later Monday morning on a petition for an injunction to prevent the camp closure.

Both the mayor and Beck said Monday morning that there was no firm deadline to remove the protesters.

"We want to make sure that everybody knows the park is closed and there are services available, that there are alternative ways to protest," Los Angeles Mayor Antonio Villaraigosa said in an interview with MSNBC.

Villaraigosa, a former labor organizer himself, earlier said he sympathizes with the movement but felt it was time it moved beyond holding on to "a particular patch of park" and that public health and safety could not be sustained for a long period.

The Los Angeles showdown follows police actions in other cities — sometimes involving the use of pepper spray and tear gas — that resulted in the removal of long-situated demonstration sites. Some of those encampments had been in use almost since the movement against economic disparity and perceived corporate greed began with Occupy Wall Street in Manhattan two months ago.

The police may be concerned with another demonstration scheduled for Monday. KCBS reports hundreds of students - angry over rising tuition fees and the pepper-spraying of peaceful protesters by University of California police - are expected to converge on the UCLA campus, as the university's regents try to meet.

Overflow crowds are expected at the James West Alumni Center on the UCLA campus in Westwood.

The UC system has been rocked by amateur video of UC Berkeley police using batons against limp protesters, and a UC Davis police officer releasing large quantities of pepper spray into the faces of sitting students who refused to move.

"Students are going to demand that the regents change the agenda to reflect their concerns," organizer Kyle Arnon told KCBS. "We are not going to be appeased if the only change is a longer public comment period."

The regents had added an additional 45 minutes to the normal 15-minute public comment period at Monday's meeting, in order to students' and faculty members' concerns about the Davis and Berkeley incidents.

No arrests at Occupy site in Philadelphia

A deadline set by the city for Occupy Philadelphia to leave the site where it has camped for nearly two months passed Sunday without any arrests.

Dozens of tents - as well as trash, piles of dirty blankets and numerous signs reading "You can't evict an idea" - remained at the encampment outside Philadelphia's City Hall Monday, the morning after a city-imposed deadline passed for the protesters to move to make way for a construction project.

The camp appeared mostly quiet amid a heavy police presence, but around 5 a.m. EST a handful of people were marching to one of the city's main business corridors banging drums.

CBS Station KYW reports that while many tents remain on Dilworth Plaza, crews from the city's Department of Streets were beginning to dispose of pallets and trash from the encampment.

KYW reports that during the partial cleanup Monday morning, workers found hypodermic needles, pill bottles and glassine bags at the makeshift tent city.

Philadelphia Mayor Michael Nutter was out of town Sunday, but his spokesman reiterated that "people are under orders to move."

The mayor himself had an exchange on Twitter with hip-hop impresario Russell Simmons, who asked Nutter "to remember this is a non-violent movement — please show restraint tonight."

Nutter's response: "I agree."

Elsewhere on the East Coast, nine people were arrested in Maine after protesters in the Occupy Augusta encampment in Capitol Park took down their tents and packed their camping gear after being told to get a permit or move their shelters.
