PORTER RANCH (CNS) – Four-year-old twin boys were hospitalized today, one in grave condition and the other in critical condition, after being pulled unresponsive from a backyard swimming pool in Porter Ranch.

Paramedics were sent to the 10000 block of Des Moines Avenue, just east of Tampa Avenue north of Devonshire Street, at about 10:35 a.m., according to the Los Angeles Fire Department and the Los Angeles Police Department.

“As LAFD Firefighter/Dispatchers provided telephone CPR guidance, LAFD Firefighter/Paramedics quickly arrived to continue advanced life support, promptly transporting the pair — one in grave condition, the other in critical condition — and their parents to a regional Pediatric Trauma Center,” said Brian Humphrey of the LAFD.

“The Mayor’s Crisis Response Team was summoned to assist the family and neighbors,” Humphrey said.

Police were investigating, according to the LAPD.
