WASHINGTON — Three people are in the hospital after a carbon monoxide leak in Montgomery County.

Montgomery County Fire and Rescue called to a house on Parkwood Drive and Parkwood Terrace, in Bethesda, detected high levels of carbon monoxide and removed three unconscious adults from the house. One person has potentially life-threatening injuries, one has serious injuries and another was taken to the hospital for precaution.

A family member found the three around 10:30 a.m.

The cause of the leak was the furnace/boiler, the gas company said.
