ANCHORAGE, Alaska (AP) — An Alaska man accused of intentionally driving a snowmobile into two Iditarod teams at speeds as high as 100 mph has appeared in court for the first time.

The Fairbanks Daily News-Miner reports that bail was set at $50,000 on Sunday for 26-year-old Arnold Demoski. He faces charges including assault and reckless endangerment after authorities say he rammed into the dog sled teams of Aliy Zirkle and four-time Iditarod champion Jeff King early Saturday.

One of King's dogs died and at least two others were injured.

Court documents say Demoski was going about 100 mph when he crashed into King's team and about 40 mph when he struck Zirkle's team.

Demoski appeared in court in Fairbanks by teleconference. Attorney Bill Satterberg declined to comment to the newspaper.
