Honolulu police officers are investigating threats on the campus of Damien Memorial School in Kalihi and Maryknoll School on Alexander Street.

The Damien campus was on lockdown, according to a social media post from the Honolulu Police Department Tuesday at 10:46 a.m.

At 1:31 p.m. HPD posted on social media that the lockdown at Damien was lifted and a terroristic threatening case opened. No arrests have been made.

Damien school officials found a note threatening students at Damien and at Maryknoll. Police officers who responded to the Damien threat learned that Maryknoll was also mentioned and officers were sent to that school.

Classes and activities at both schools are canceled for the rest of the day.

Founded in 1962, Damien is a private Catholic school for boys and girls in grades six through 12.

Blessed in 1927, Maryknoll School is also a co-educational private school for about 1,000 students across all grade levels supported by about 150 faculty and staff.
