A 4-year-old boy nearly drowned at the Adagio Condominium complex near Vegas and Buffalo drives just before 2:30 p.m. on Saturday.
Metro police said the toddler was swimming in a pool with other children when the designated supervising adult left other adults in charge to change into a swimsuit.
A few minutes later, a 10-year-old spotted the boy at the bottom of the pool and notified adults.
Las Vegas Fire and Rescue crews arrived on scene and successfully revived the 4-year-old. He was transported to Sunrise Hospital and Medical Center where he remains in critical condition.
