SCOTTSDALE, AZ — A 3-year-old boy is in critical condition after he was pulled from a backyard pool in Scottsdale on Saturday afternoon.

Fire officials say it happened near 124th Street and Via Linda around 2:44 p.m.

When crews arrived, CPR had begun on the toddler. Crews then transported the boy to a hospital.

It is unclear how long the child was in the water.

The Scottsdale Fire Department urges everyone to practice vigilant water safety:

Designate a responsible adult as a "Water Watcher" whose only job is to actively supervise children around the water.

• Never leave children unattended in or near a pool, even for a moment.
• Install and maintain barriers, self-closing and self-latching gates, and other layers of pool protection.
• Learn CPR. Immediate bystander CPR can significantly improve outcomes during a drowning emergency.
• Ensure children wear properly fitted U.S. Coast Guard-approved life jackets when appropriate, but remember that life jackets are not a substitute for close adult supervision.
• Keep phones and other distractions away while supervising children around the water.
• Drowning can happen silently and in seconds. Constant, attentive supervision is the best way to prevent a tragedy.

The investigation remains ongoing.
