The search continues for a 15-year-old boy who was last seen swimming with his brother in the ocean off the shoreline of Coney Island Thursday.

Witnesses report last seeing the teen about 30 feet west of a jetty near West 22nd Street when a current came and swept him under the water.

The teen was with his 14-year-old brother in the water before they both began struggling to swim. The 14-year-old boy was rescued by good Samaritans.

The city’s Department of Parks and Recreation said that part of the beach was not staffed with lifeguards at the time. Red flags warn beachgoers not to swim there.

“If you don’t know how to swim, go back.” That’s what 70-year-old beach goer Fernando Agurto said he told the brothers before the incident occurred.

Not long after that, Agurto said he heard yelling.

“The lady says, ‘Oh, someone is drowning, so I ran,’” Agurto said. “So we grab one with the help of another guy. Two other guys. So we grab him. I say, ‘Can you walk? Just go on, get out of here.’”

At the same time he said he ran to rescue the brother, another two good Samaritans sprang into action and began working with Agurto to help the teens.

"He was just very tired very exhausted,” beachgoer John Mclean said. “We just got him out in time.”

Agurto said he hurt his leg on the rocks, so he wasn’t able to go after the second teen.

McLean and his friend Benjamin Colon said they tried their best to do so.

“’Get my brother, get my brother,’” Colon said the 14-year-old teen told all three men when they pulled him from the water. “So I tried to when I was over on the rocks. The current was pulling me this way, so when I see his brother’s head bobbing, the wave came and just took him under. So me and him went back this way and started searching.”

That’s the last time anyone saw the 15-year-old boy.

Eventually, dozens of lifeguards arrived along with emergency responders. Together, they launched an effort to find the teen by searching from land, air and sea.

In a tweet about the incident, Councilmember Ari Kagan shared information the NYPD shared with him, which said, “The family currently lives in a shelter in the Bronx and has close friends here in Coney.”

The NYPD said members of the 60th Precinct have visited with the family and are assisting in whatever ways they can.

In a statement, officials with the Department of Parks and Recreation said: “We’re saddened by today’s tragic event and our thoughts are with the young man’s family during this time.”
