An Ankeny chiropractor facing multiple sex abuse, assault and exploitation charges turned himself into police on Friday.

Ankeny police began investigating Joshua Blake Hanisch, 39, after the Department of Human Services notified police on March 30 that Hanisch had possibly sexually abused three minors, according to Lt. Brian Kroska, spokesman for the Ankeny Police Department.

After further investigation, police discovered three more victims of sex abuse.

All six victims are females under the age of 12, Kroska said. It is unknown if the minors were Hanisch's clients.

Hanisch is charged with four counts of second-degree sex abuse, two counts of assault with intent to commit sexual abuse, two counts of sexual exploitation of a minor, and four counts of possession of a controlled substance.

Kroska said drugs were found as authorities executed search warrants at his Ankeny home, his business in Des Moines and a property he owns in Perry.

Kroska could not immediately confirm further details.
