The International Skating Union is investigating a Team U.S.A. figure skater for allegedly slashing her rival's leg.
Mariah Bell, 22, collided with South Korean skater Lim Eun-soo, 16, during a warm-up session at the World Figure Skating Championships in Japan, leaving Lim with a cut to her left calf.
Lim's agency has accused Bell of intentionally trying to injure her competitor with her skate blade during the crash.
These photos from skating photography Twitter account thelittlepicks capture the incident as it happened:
Lim was reportedly skating around the edge of the rink when Bell skated up from behind her and suddenly kicked out, striking Lim on the leg.
A representative for the agency All That Sports told Yonhap News they believe "this is not a minor situation that can happen in an official rehearsal."
"We have asked the Korea Skating Union to file an official complaint against Mariah Bell for her intentional infliction of Lim Eun-soo's injury."
The agency also said that Bell has not apologized for the incident.
An official with the Korea Skating Union told the Washington Post that "at this stage" they can't conclude Bell deliberately injured Lim.
"It is hard to tell just by watching the video footage of the incident."
Lim went on to compete after her leg was bandaged, and finished the day in fifth place while Bell trailed her in sixth place.
While both skaters actually train together in Los Angeles under the same coach, Lim's agency added that Bell has been "bullying" her training partner for months, and say she verbally confronted Lim before the competition.
While neither skater has weighed in on the accusations, fans are already comparing Bell to Tonya Harding, the skater who was banned for life from international competition for her part in an attack against her rival, Nancy Kerrigan.
