The raid was conducted after police received multiple complaints about the man beating up customers "to heal them." 

Kalak last year left Iraqi Kurdistan, where he was being sought, and continued his "practices" in Saudi Arabia. He was arrested in February of last year in Medina, before resurfacing in Istanbul's Başakşehir.

Kalak has garnered controversy through videos that purportedly show him healing the sick, possessed and people with disabilities using Quranic verses.

Hundreds of people visited Kalak's office in Istanbul after he advertised his "healing practices" on social media. One of his customers, a parent to a child with autism, recorded his beatings and showed them to the police.
