A MAN has been arrested in connection with the horrific fertility clinic bombing triggered by a sick “anti-human” attacker.

Daniel Park, 32, was nabbed at the John F Kennedy International Airport in New York City on Wednesday, weeks after suspected bomber Guy Bartkus died in the explosion.

It’s unclear why the suspect was arrested, but he may have provided material assisting the attack, an official close to the investigation told CBS News.

Park, who is from Kent, Washington, a suburb of Seattle, is set to appear in federal court in Brooklyn, New York, on Wednesday afternoon.

The shocking twist came after Bartkus, 25, drove a Ford Fusion right beside the American Reproductive Services fertility clinic in Palm Springs, California, on May 17.

The car suddenly exploded into a fire bomb, injuring four bystanders in the massive blast and killing the attacker.

However, no one was at the clinic at the time of the attack, and all of the embryos inside were saved.

The blast could be felt within a mile radius, and officials said it was far too sophisticated to have been triggered by crude explosives like fireworks.

Detectives believe that Park likely acted alone at the site, but may have had help buying parts or building the bomb.

Investigators linked a disturbing website to Bartkus where he’s believed to have penned unhinged ravings about his “nihilistic ideations.”

The author wrote that he was going to “war with pro-lifers” and wanted to target the IVF clinic because he wanted to sterilize “this planet of the disease called life.”

In a recording on the site labeled “pre,” the speaker said, “Basically, it just comes down to I’m angry that I exist and that, you know, nobody got my consent to bring me here.”

After hearing news of the attack, Bartkus’ devastated father admitted that he noticed eerie red flags in his son when he was little.

He said that Bartkus liked to play with fire and burned down their home at just nine years old when he was messing around with matches, Richard Bartkus, 75, told KTLA.

“After he had burned the house down, he started changing a little bit, he’d light fires,” said the dad.

“I was too strict for him, so he wanted to stay with mom until the divorce came through. Mom was lenient.”

Richard described his son as a “smart, good kid” and “a follower who was easily influenced by others.”

Despite noticing the now-glaring signs of violence, Richard said he couldn’t imagine his child ever committing such a brazen crime.

“We hadn’t talked in over 11 years, and now I won’t see him again,” said Richard.
