The Harris County Sheriff's Office said Saturday night the man was 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 areas adjacent to the room had been evacuated. Ambriz said, "the hospital is safe, the patients are safe."

TOMBALL, Texas (AP) -- Authorities now say they do not consider an incident at a Texas hospital involving a distraught father to be a hostage situation.

Original story below.
A man has taken at least two hostages at a Houston-area hospital, police confirmed.
According to the Harris County Sheriff's office, early indications are that the hostage-taker is a "distraught" father of a patient. It is unknown if he is armed.
The situation is unfolding in the northern suburb of Tomball at the Tomball Regional Medical Center.
A supervisor at the county's emergency dispatch center said the situation was in the critical care unit and began around 7 p.m.
According to Detective Jimmy Harral with the Tomball Police Department, the man is believed to be armed and has barricaded himself in a room. Authorities are negotiating with the man for a "peaceful surrender" and no shots have been fired:
KPRC-TV reporter Anoushah Rasta said the police are characterizing the situation as "very contained":
The hospital is reportedly not on lockdown or been evacuated, but it is not accepting new patients through the emergency room because it is blocked by police.
KTRK-TV has raw video from the scene:
The same outlet reports the man is believed to be armed and has barricaded himself in a room with a patient and a family member, but he is not making demands.
Rasta has posted photos of a SWAT team responding to the scene:
