Authorities say a carbon monoxide leak at a South Texas hotel blamed on a water heater has sent 12 guests to a hospital but all should recover.
The San Antonio Fire Department reports the leak was discovered around 2 a.m. Tuesday as firefighters responded to calls about sick guests at a Comfort Suites Hotel.
Department spokesman Joe Arrington says leaking carbon monoxide was traced to an exhaust pipe that accidentally dislodged from a gas-powered water heater.
The latest news from around North Texas.
Firefighters evacuated more than 100 people from the Comfort Suites Hotel, as a precaution. Arrington says 12 guests taken to a hospital have conditions not believed to be life-threatening.
Fans were used to ventilate the hotel. Arrington says guests were allowed to return several hours later.
