A Bahamas dad watched in horror as his 5-year-old son was swept away in shark-infested waters as Hurricane Dorian raged, according to a new report.

Adrian Farrington, 38, of the Abaco Islands, was outside Sunday with his son Adrian Farrington Jr. — nicknamed “AJ” — when he saw sharks, brought by the storm surge — practically at his doorstep, he told The Nassau Guardian.

“So, I grabbed my son and I put him on top [of] the roof,” Farrington told the paper. “The water was high on the roof.”

He tried to comfort the terrified boy, he recalled.

“I keep telling him, ‘Don’t cry. Close your month. Don’t cry. Keep breathing. Don’t cry. Close your mouth,’” he said.

But then the situation turned tragic.

“Before I could sit on the roof to hold him, the gust from the hurricane dragged him across the roof back into the surge on the next side,” Farrington said. “I still could remember him reaching for me and calling me, ‘Daddy!’”

He pushed aside debris as he struggled to find his son — but saw nothing when he went underwater, he recalled.

“I was like feeling to see if I could feel some kind of cloth, some kind of clothes, some kind of skin, flesh, tennis, something,” Farrington told the paper through tears.

“I ain’t find nothing,” he said. “I come back up. I hold my breath and I gone back down again. All this time, people carried my wife to safety and they calling me, but I ain’t want to go because I didn’t want to leave my son.”

He didn’t give up right away, but ultimately grew exhausted from battling the surges, he told the paper.

He found his way to a church — that was “moving like when you put clothes on the line on a breezy day.”

“Everybody else who was inside, they run to try to hold the wall and I watched the wall and the roof crush everybody inside the church,” he said.

“There’s a guy, I could see him,” Farrington recounted. “I tapped on him and I asked him if he was OK. I ain’t get no response.”

In all, Farrington believes he watched 12 to 15 people die in less than an hour.

Then some local residents carried him to a clinic, and he was flown to a Nassau hospital to be treated for lacerations on his hand and two fractured bones in his right leg.

From there, he told the paper he wasn’t sure what would become of his son.

“If he [is] rescued, I praise the Lord,” Farrington said. “But for the surge, what I saw when I [lost] him, anything could happen. You had sharks swimming in the water, anything could happen.”

Meanwhile, a post on an Abaco Islands Facebook page urged local residents to come forward if they’ve seen the boy.
