Protesters in Brooklyn — some chanting “where is ICE?” — besieged a second nail salon Monday that they believe is connected to the shop where customers brawled on video with employees last week — forcing cops to escort the workers out for their own safety.

About 150 predominantly African-American demonstrators marched from New Red Apple Nails at 1426 Nostrand Ave. — scene of the melee caught on tape Friday — to the Beautiful Red Apple Nails at 1224 Nostrand Ave. and trapped four employees inside.

It wasn’t immediately clear if the two salons are related. But police were ready for protesters and were inside the business when they arrived at about 6:30 p.m.

Demonstrators angrily chanted, “shut them down,” “f–k the police” and “no nails, no toes, these racist shops have got to go.” At least one protester screamed, “where is ICE (U.S. Immigration and Customs Enforcement)?” implying that the salon’s Asian employees might be undocumented immigrants.

Cops formed a line to hurry the employees, three women and one man, into a police van.

Shortly after the workers were driven away, several protesters and cops shoved each other but there were no immediate arrests.

Hours earlier, officers had to do the same thing back at 1426 Nostrand Ave. and helped employees get through protesters to safety.

Monday’s demonstrations were sparked by a scuffle Friday when customers and employees fought over a disputed $5 eyebrow wax job.

Employee Huiyue Zheng, 32, and customer Christina Thomas, 21, were busted for a variety of charges including misdemeanor assault, harassment and menacing. Zheng was caught on surveillance tape chasing a combatant out of the salon with a broomstick.
