The authorities in Las Vegas swooped down in a dramatic raid on Tuesday, arresting the notorious leader of an alleged cult. Nathan Lee Chasing His Horse, better known as Nathan Chasing Horse, was taken into custody following allegations of heinous crimes committed against young Indigenous girls over the course of two decades.

The former actor, who starred in “Dances With Wolves,” was apprehended near his sprawling North Las Vegas home, where he is rumored to have lived with his five wives.

Swat officers were seen outside the two-story home in the evening as detectives searched the property.

Known for his role as the young Sioux tribe member Smiles a Lot in the Oscar-winning Kevin Costner film from 1990, Chasing Horse gained a reputation among tribes across the US and in Canada for performing healing ceremonies and spiritual gatherings. Police allege he used his position to abuse young Indigenous girls.

His arrest is the culmination of a months-long investigation that began after police received a tip in October 2022. According to a 50-page search warrant, Chasing Horse is believed to be the leader of a cult known as the Circle.

State attorneys general and lawmakers around the US are looking into creating specialized units to handle cases involving Indigenous women.

In South Dakota, the attorney general’s office renewed focus on crimes against Indigenous people, including human trafficking and murders.

Las Vegas police have identified at least six alleged victims and uncovered sexual allegations against Chasing Horse dating to the early 2000s in states including Montana, South Dakota and Nevada, where he has lived for about a decade.

There was no lawyer listed in court records for Chasing Horse who could comment on his behalf as of Tuesday evening.

Chasing Horse was born on the Rosebud Reservation in South Dakota, which is home to the Sicangu Sioux, one of the seven tribes of the Lakota nation.

According to the warrant, he was banished in 2015 from the Fort Peck Reservation in Poplar, Montana, amid allegations of human trafficking.

“Nathan Chasing Horse used spiritual traditions and their belief system as a tool to sexually assault young girls on numerous occasions,” it reads, adding that his followers believed he could communicate with higher beings and referred to him as “Medicine Man” or “Holy Person”.

Although the warrant includes details of crimes reported elsewhere, the arrest stems from crimes allegedly committed in Clark county, Nevada. They include sex trafficking, sexual assault of a child younger than 16 and child abuse.

Some of the alleged victims were as young as 13, according to the warrant. One of Chasing Horse’s wives was allegedly offered to him as a “gift” when she was 15, while another became a wife after turning 16.

Chasing Horse also is accused of recording sexual assaults and arranging sex with the victims for other men who allegedly paid him.
