PORTLAND, Ore. (KOIN) — Two people were seriously wounded when they were stabbed multiple times at a Northeast Portland apartment in the early hours of Saturday.

A 53-year-old man was arrested at a nearby apartment in the complex at 8231 NE Broadway shortly before 3 a.m. Michael J. Thomas was booked on 2 charges of assault.

On Monday, the Multnomah County District Attorney’s Office said these charges were dropped at this time to allow more investigation. However, these or other charges could be re-instated in the future.

Police said the victims and Thomas were involved in a “disturbance” in the parking lot at the apartment building and that during the altercation the victims were each stabbed multiple times. Investigators said they believe they found the knife used in the attack.

They were taken by ambulances to Portland hospitals for treatment and are expected to recover.
