A 39-year-old Waipahu man was in police custody after allegedly attacking his two sisters with a large wooden stick during an argument Sunday over a family inheritance issue.

The sisters told police they were arguing with their brother about 4:30 p.m. when he took out the stick and hit the younger one, 30, four times on the upper torso.

They said he then attacked the older sister, 45, hitting her on the head and elsewhere numerous times.

Police said the two sisters were taken to the hospital and admitted for treatment.

Patrol officers were sent to the brother's home on Waipahu Street and arrested him on suspicion of attempted murder and second-degree assault.
