After emergency sirens were heard across O'ahu and on Maui, the falsehood of the alert had many flashing back to another false alert.

In January of 2018, residents and visitors received the following message:

"BALLISTIC MISSILE THREAT INBOUND TO HAWAII.  SEEK IMMEDIATE SHELTER.  THIS IS NOT A DRILL."

However, after about 30 minutes, another alert was sent out later saying, "There is no missile threat or danger to the State of Hawaii.  Repeat.  False alarm."

During the time in between the initial alert and the confirmation that it was false, many were in a frenzy. One man said he even suffered a heart attack because of the news.

The State of Hawaii released the following statement regarding the false emergency sirens heard Wednesday:

"Due to an error during a Honolulu Police Department training exercise, emergency sirens were mistakenly activated on Oahu. There is no emergency at this time."
