Police arrested a 48-year-old man for allegedly assaulting his 74-year-old mother at her Ewa Beach home.

Police said the man used to live with his mother, and while at her home 7 p.m. Tuesday, he allegedly assaulted her during an argument and fled.

The woman received substantial bodily injury, police said.

The son showed up at the house again Wednesday, and officers arrested him on suspicion of second-degree assault.

The woman has a temporary restraining order against her son because of prior incidents.
