A 28-year-old man was arrested Tuesday morning after he allegedly broke into his ex-girlfriend’s Kalihi Valley home and assaulted her.

The suspect entered the residence of a 30-year-old woman around 8 a.m. and assaulted her, police said. After accompanying the victim to her car to retrieve personal items, the suspect again assaulted the woman, police alleged.
