The nonagenarian clobbered by a cane-wielding thug in Manhattan recalled his harrowing experience Saturday, telling The Post the random and unprovoked attack has left him bloodied, and bewildered.

“They hit me with a big bat,” Juan Llorens, 91, said at his home Sunday. “I don’t know who it was. He was young and skinny. He just kept beating me.”

Llorens was strolling on Broadway near his home on West 204th Street in Inwood just before 6 p.m. Friday, when a younger man walking by with a cane suddenly turned around and kicked Llorens’ shopping cart like a football.

The attacker then walloped the senior on the side of the head with the walking stick in a brutal assault caught on surveillance video.

The elderly man says he’s grateful for the Good Samaritans who stepped in to stop the beating. He has already forgiven the attacker — but is still flabbergasted as to why the younger man suddenly snapped.

“I don’t understand how someone can just attack someone like that. This is someone who is very dangerous,” he said.

The Cuban immigrant was taken to the hospital, where doctors had stitched up his badly injured left ear — leaving droplets on his shirt.

The attack is especially shocking because it happened in broad daylight in the neighborhood where Llorens has lived since fleeing Communist Cuba in 1968.

But now he’s shaken about going outside, his son told The Post.

“He’s intimidated now,” said Llorens’ son, who is also named Juan, and now 53. “He’s a little nervous.”

Llorens was a history teacher back in Cuba, and started life over in the US, where he took a job as a butcher on 137th Street, working six days a week to make a new life for his small family, said his son.

And he hasn’t stopped in his twilight years — he still collects bottles and cans around the neighborhood, where he is a beloved local fixture .

“He’s always outside, he goes to the bodegas people spend time talking to him,” the younger Llorens said. “My son thought he was the mayor of New York because everybody stops him, everyone knows him.”

The old man is tough as nails in spirit — police had to call his son to convince him to go to the hospital after the attack — but had no way to defend himself against his crazed attacker, his son said.

“When there’s a heavy wind, he’s going to be like a kite. He’s not going to fight nobody. he has a hard time cutting a piece of cheese,” said the son.

Locals were horrified the see the cowardly assault on the neighborhood icon.

“It was a defenseless old man,” said Gema Oberholtzer, who owns a wig store right outside the site of the assault and witnessed the attack. “There was no motive, no reason for that to happen.”

Cops are still looking for the assailant, believed to be 5-foot-10, about 150 pounds and between 20-and 30-years-old.

He was wearing headphones, a blue New York Yankees cap, a black T-shirt over a gray long-sleeved shirt, blue pants with checker-box print and black sneakers at the time of the attack, cops said.
