FRENCH CAMP — San Joaquin County Sheriff's deputies responded to San Joaquin General Hospital's emergency room at 2:49 p.m. Tuesday after a report of a disturbance.

When they arrived, the suspect was barricaded in one of the emergency treatment rooms.

The suspect was later identified as 53-year-old Robert Johnson. He had been treated and was awaiting transportation back to St Joseph’s Behavioral Health Center. When medics arrived, Johnson charged at medics with a broken piece of plastic, attempting to stab them, according to the Sheriff's Office. He retreated and barricaded himself in the treatment room.

The emergency room was placed on lockdown and efforts were made using the San Joaquin County Hostage Negotiating Team to talk Johnson out of the room. When those attempts failed, a deputy outfitted his K9 partner with his newly acquired stab-proof vest. Akky was sent into the room and quickly subdued Johnson.

Johnson was medically cleared and was booked into the San Joaquin County Jail for assault with a deadly weapon, battery on emergency personnel and resisting arrest.
