A 3-year-old boy tumbled out of the second-story window of a San Mateo home Monday evening in what a police sergeant said was a "tragic accident.”

The toddler, who was conscious and crying directly after the incident, was transported to a nearby trauma center. Any further information on his condition has not been released.

The incident occurred in the first block of South Grant Street in San Mateo’s North Central neighborhood at 5:10 p.m. Monday, Sgt. Dave Norris said.

"By all accounts it appears to have been an accident,” Norris said. "There is no indication of any criminal activity or foul play involved in this incident.”

Norris said it is important for parents to remember that young children — especially toddlers — are very active and curious.

"Although not every accident can be predicted, parents and families should remember that predictable is preventable, and take measures to secure their home environments as best they can to prevent foreseeable dangers,” he said.
