A WITNESS has described the devastating moment they saw a child being pulled from a pool before she was pronounced dead.

The nine-year-old girl was visiting the Boardwalk at Hersheypark in Pennsylvania on Thursday when she suddenly fell into distress.

Lifeguards immediately performed a rescue and gave CPR before the child was rushed to the hospital, but she couldn’t be saved, Hersheypark’s CEO John Lawn confirmed.

While few details have been released about the child’s death, one witness claimed they saw her being pulled from the wave pool, according to NBC affiliate WGAL.

This comes as the wave pool was closed on Friday while the rest of the park operated as normal, the outlet reported.

The witness said they were “heartbroken” after watching the child “being pulled” from the pool.

“Lifeguards blew their whistle, evacuating everyone, and within moments, staff and security rushed to help,” the witness, who asked to remain anonymous, said.

The parkgoer said that a lifeguard performed CPR on a gurney “with intense focus” and worked for several minutes.

Staff at the park “did their best to shield onlookers from the trauma, but the weight of the moment was overwhelming,” according to the witness.

That night after getting home from the park, the witness said they couldn’t sleep because they were so shaken by the death.

The parkgoer described the tragedy as “something I’ll never forget,” but stressed how they were struck by the “staff’s compassion.”

Lawn mourned the death of the child and confirmed that his staff worked tirelessly to try and save her.

“Our hearts break for this child and the child’s family,” he wrote.

“We extend our deepest condolences for their loss.”

The CEO said that he will be conducting a “thorough internal review” alongside authorities in the coming days.

“To every family who visits Hersheypark, please know this: your safety and well-being drive every decision we make,” he said.

“We will thoroughly investigate this tragedy and honor the memory of this young guest by continuing our focus on ensuring the safety of our guests at Hersheypark.”

The wave pool holds 378,000 gallons of water and slowly rises from zero to six feet, according to the park’s website.

It’s part of the Boardwalk, which boasts a Lazy River, tall water slides, and cabanas for relaxing by pools.

The amusement park is in Hershey, about two hours west of Philadelphia, and is owned by the chocolate company Hershey.

It was originally built by the confectionery company’s founder, Milton S Hershey, as a place where employees could go to relax.

The tragedy comes as a toddler plunged to their death at a water park after slipping from their dad’s arms.
