Police arrested a 63-year-old man who allegedly attacked his roommates, both men ages 42 and 57, yesterday afternoon.

Police said the suspect choked one of his roommates who was watching television.

When another roommate tried to intervene, the suspect grabbed a knife from the kitchen and threw it at the second roommate, police said. There was no known reason for the alleged attacks.

Police arrested the man at the Puuku Makai Drive home, for abuse of a family member and two counts of terroristic threatening.
