(CNN) — An accident on a children's swing ride at a festival in Norwalk, Connecticut, on Sunday injured 13 children, some seriously, according to police.
The ride "apparently lost power causing the children on the ride to forcefully fall to the ground," Norwalk police said on the department's Facebook page.
Most of the injuries were minor, police said, but "several" were seriously injured, "including two which appeared to be the most serious."
The accident occurred at Norwalk's annual Oyster Festival. Other rides were closed after the incident, and officials were weighing whether to reopen them for the remainder of the festival.
