Helicopter crashes into water at Pearl Harbor

The Coast Guard said five people were aboard the helicopter Thursday. Coast Guard Petty Officer Melissa McKenzie says it was civilian helicopter, "possibly a news chopper."

McKenzie says all five people were transferred to land after the hard landing, which occurred near the Arizona Memorial, a popular tourist destination in Oahu.

According to KHON, witnesses said the helicopter came to rest upside-down. Bystanders reportedly dove into the water to free passengers from the wreckage.

A Honolulu Emergency Services Department spokeswoman confirms one victim was in critical condition.

The Coast Guard received notification of the accident at 10:25 a.m. local time.

The FAA said that the helicopter involved is a Bell 206 helicopter.

Tours in the vicinity have been cancelled.
