An Idaho psychiatrist has been arrested for allegedly raping a patient with a foreign object.

Boise police said they investigated the claim for nearly a month before taking 45-year-old Alexander Wills into custody on a charge of forcible penetration by use of a foreign object.

Police said they were called about the incident on September 2 by a woman who told them Wills “made aggressive physical contact” with the victim and raped her with a foreign object.

A biography for Wills at Psychology Today says he is a graduate of the Sackler School of Medicine and owns PERMA Mental Health and Ketamine Clinic, a practice with offices in several Idaho locations. A website for the clinic has been locked down behind a password.

Wills is also the author of a self-help book, “Give a F*ck, Actually.”

He was arrested on September 30 and is being held on a $500,000 bail, although jail records also say he is on a “booking hold.”

Police also said they were “concerned that there may be additional victims” and urged anyone with more information to call Ada County Dispatch at 208-377-6790 or visit the Ada County Victim Services Center.
