Police have two men in custody and have opened an attempted murder investigation following an early-morning stabbing at McKinley High School.

Emergency Medical Services reported that a 43-year-old man was taken in serious condition to the hospital with multiple stab wounds at 2:24 a.m. from the school at 1039 S. King St.

The suspects, ages 20 and 21, were arrested on suspicion of second-degree attempted murder at 2:30 a.m.

The 20-year-old suspect gave no local address when he was arrested.

The 21-year-old suspect, who gave a Kalihi address, was fined last year for having an open liquor container in a car.
