A 37-year-old Ewa Beach man was arrested yesterday after a woman told police he threatened to kill her while she was driving on the freeway last week.

The woman told police she was heading east on H-1 Freeway about 2:15 p.m. Aug. 23 and was nearing the Waipahu off-ramp when the man abruptly grabbed the steering wheel, nearly causing a collision.

The woman told police that she had three children with the man and is in the process of ending their 18-year common-law relationship.

The woman said that after the man grabbed the wheel, he pulled out a large cane knife and threatened to kill her.

After emotions subsided, she dropped the man off at a relative's home, the woman told police.

She left the area and called police, who later located the man and arrested him on suspicion of first-degree terroristic threatening.
