Twelve people, including several children, were taken to a hospital Saturday evening after too much chlorine was put into a lazy river pool in Houston, Texas creating a hazardous situation, police said

According to the Houston Fire Department, the accidental chemical spill happened just before 5 p.m. on Saturday, June 24. Hazmat cleaning services were sent to clean the infected pools, authorities said. 

Houston Fire Department Chief Samuel Peña said the scene is still active and fluid and asked that people "please stay clear of the area due to ongoing emergency operations."

Four hours following the incident, authorities said that the "incident is under control," but they did not share the conditions of those who went to the hospital or how the spill occurred.
