A Carnival cruise ship passenger was critically injured Tuesday after a 16-foot fall and was airlifted to New Orleans for expert treatment.

According to reports, the 23-year-old man suffered “multiple significant injuries” as he fell from the cruise ship’s balcony.

The Carnival Valor was sailing 65 nautical miles from Venice off the coast of Louisiana when the mishap occurred, per Coast Guard.

It remains a mystery how the man fell. His identity has been kept confidential by the authorities.

A Coast Guard news release said the injured person has been airlifted along with the ship’s doctor, to University Medical Center in New Orleans, where he is said to be critical.

According to cruise news, watchstanders in Coast Guard New Orleans got a call at 1:14 a.m. for the medevac of a 23-year-old man. They deployed an MH-65 Dolphin helicopter with aircrew from the Coast Guard Air Station in New Orleans.

The aircrew arrived on the scene at 5:45 a.m and transported the injured man and a doctor to New Orleans University Medical Hospital.

Carnival cruise also updated that the man was first evaluated by the ship’s medical team, who found that he needed broader evaluation and medical support.

“We can confirm that the guest did not fall in the water but rather was injured on deck,” per the spokesperson.

The ship was on a 5-day trip Caribbean expedition and had more than 4,000 passengers under various cruise deals.

Carnival Valor departed from New Orleans on Monday.  It has now reached Cozumel, Mexico on Wednesday morning.
