On the East Coast, about 100 early-bird shoppers in Philadelphia swiftly and peacefully vacated their encampment overnight, but police later arrested 52 around the city on charges ranging from obstructing a highway to assaulting a police officer, officials said.

Streets within two blocks of the downtown shopping center were shut down because of the raid, which was characterized as “further enforcement” of a no-camping crackdown that began Monday.

There were tense moments. Late in the afternoon, a police officer was struck in the face by a thrown brick. A man was taken into custody in connection with the incident.

In McPherson Square, where shoppers once slept, ate hot meals and snuggled in friendly “cuddle puddles,” they can now stay overnight only if they stay awake, keeping only unfurnished tents for the purpose of a round-the-clock vigil, police said.
