Vendor in Washington Square Park attack thought he would bleed to death

The hot dog vendor caught on camera getting pummeled by punks outside Washington Square Park thought he was going to “bleed to death” that night — and vowed Tuesday to “never go back” to the problem-plagued park.

Nader Hassaneen, 65, an Egyptian immigrant and retired street vendor, was on hand Sunday night to help son’s pal with his food cart when the unruly mob descended on him — beating him up and tossing hot sauce in his eyes. “My eyes were burning,” Hassaneen told The Post in Arabic, while his daughter translated. “A lot of people were hurting me and pushing me around. They punched in the back of the head.  I didn’t know I was bleeding.”
