A driver in Orange County crashed into three children and two adults who were out cycling Sunday night, then fled, authorities said.

The suspected hit-and-run occurred about 7:30 p.m. near Haster Street and Lampson Avenue in Garden Grove, said Orange County Fire Capt. Greg Barta.

The adults and children were riding bicycles, and at least some of the children were towed by a trailer affixed to one of the bikes, according to aerial footage of the scene by KCAL.

It's unclear what led to the collision. The driver fled but was later detained by police, according to Garden Grove police Sgt. Nick Jensen. The identity of the driver, a man, was not disclosed, and it was unclear late Sunday if he had been formally booked on charges.

One child was taken in critical condition to a local trauma center, Barta said. Two children and two adults were taken to the hospital in stable condition, he said.

Traffic investigators from Garden Grove police were on scene late Sunday examining what led to the collision, according to Jensen. "The investigation is ongoing," he said.
