TOMBALL, Texas » Authorities say the father of a patient at a Texas hospital who became distraught over his son’s condition has surrendered without incident. They said he did not have a weapon.

The Harris County Sheriff’s Office said Saturday night that the man had been with his adult son inside a hospital room in the critical care unit of the Tomball Regional Medical Center. Authorities had earlier said they believed he was holding at least two hostages.

Harris County Sheriff’s Lt. Joe Ambriz said a threatening situation arose around 7 p.m., but wouldn’t describe it or any details about the son’s condition. Authorities said around 11 p.m. that the man was in custody and the hospital was no longer under any lockdown.

The hospital is about 30 miles northwest of Houston.
