In the days following Zac Efron's swimming accident, we're learning more about what caused the actor to be hospitalized in Spain.
An inside source confirmed to People magazine that Efron and his friends, who were staying at a villa in Ibiza, went to go swim in the property's pool.
Efron reportedly dove into the water, knocking his chest against the bottom of the pool and ingesting water into his lungs.

Security at the Spanish villa noticed the 36-year-old actor in distress, and helped to pull him out of the water. Efron was in a brief daze after being removed from the pool, and taken to the hospital for cautionary purposes.
According to People magazine's source, he had X-rays taken of his chest to make sure no water was left in his lungs and was medically cleared within hours of his arrival. Efron's departure was stalled due to paparazzi that had followed him to the hospital. He left once they were gone. TMZ first reported the news.
