A second man was pulled out of the water at Playa Cocles in Costa Rica — caught in the same rip current that drowned “The Cosby Show” star Malcolm-Jamal Warner at age 54.

Costa Rican first responders treated a second person at the scene where the actor was declared dead Sunday, officials confirmed The Post.

Paramedics received reports of a “water-related” incident in Cahuita, Limón, at around 2:10 p.m. on Sunday. Once they arrived at the scene, they attended to two adult male patients.

Authorities said that “two people were dragged by a water current at the beach,” though did not disclose any additional information.

One man, who has not been named, was rushed to a local clinic in critical condition.

First responders performed CPR on the second individual, who was identified as Warner, but the actor was pronounced dead at the scene.

“The scene was subsequently handed over to … authorities for the appropriate legal procedures,” the local Red Cross told The Post.

Costa Rica’s national police told The Post on Monday that Warner was pulled from the water by people in the area and taken to shore, where they desperately attempted to save his life.

The actor’s body was taken to a morgue in San Joaquín de Flores for an autopsy. His cause of death is listed as asphyxiation by “submersion,” officials said.

Warner was propelled to fame after landing the role of Theo Huxtable, the son of Bill Cosby’s Cliff Huxtable, in “The Cosby Show,” which ran from 1984 to 1992.

The gig landed him an 1986 Emmy nomination for Supporting Actor.

In 2021, the actor spoke to The Post about the hit show’s legacy, two months before Cosby’s sexual assault conviction was overturned.

“I can understand why some people can’t watch the show and enjoy it because of everything that’s going on now,” Warner told us.

“But I think … there’s a generation of young people who have pursued higher education or have started loving families because of the influence of that show. So it’s kind of like, you can’t discount its impact on television culture and American culture.”

The hit sitcom also featured Phylicia Rashad (Clair), Sabrina Le Beauf (Sondra), Lisa Bonet (Denise), Tempestt Bledsoe (Vanessa) and Keshia Knight Pulliam (Rudy).

After the show wrapped, Warner continued to work in showbiz for decades, acting onscreen and in voiceover.

Warner voiced the Producer in “The Magic School Bus” from 1994 to 1997. His next major role came in 1996 when he was cast as Malcolm McGee in “Malcolm & Eddie.”

Warner starred in all 89 episodes alongside Eddie Griffin until the sitcom went off the air in 2000.

In 2018, Warner joined “The Resident” as Dr. AJ Austin, whom he played until 2023.

Some of his other credits include “American Horror Story: Freak Show,” “American Crime Story: The People v. O.J. Simpson,” “Suits,” “9-1-1,” “Community,” “Sons of Anarchy,” “Here and Now” and “The Fresh Prince of Bel-Air.”

Warner is survived by his wife and daughter.
