Hawai‘i Island police have initiated a first-degree terroristic threatening investigation after being informed of a threat made on Konawaena School Road near Konawaena High School in Kealakekua.

On Friday, police responded after a school custodian reported seeing a firearm (not pointed at anyone in particular) inside a passing silver-colored SUV containing four males.

Police located the vehicle at a nearby residence and arrested three 18-year-old males and one juvenile for first-degree terroristic threatening. Konawaena High School was placed on lockdown for 45 minutes as a safety precaution.

Upon further investigation, police believe the item to be a construction tool, which at this time is not believed to have been used in a malicious manner. The four males were released from police custody pending investigation. The incident is an ongoing investigation and the case is being investigated by detectives with the Area II Juvenile Aid Section.

Police ask anyone with information regarding this incident to call Officer Christopher Ross at (808) 326-4646, ext. 302.
