A religious leader is charged with a string of sexual offences against some of his students.
Mohammad Masroor, 48, of Toronto, faces 13 charges and is believed to have traveled extensively around the world, raising fears there are other victims.
The man was arrested Aug. 10 in a case involving five people, both male and female.
He is the Imam of the Baitul Mukarram Islamic Society on Danforth Ave.
He has lived in Asia, Europe and most recently Florida, Michigan and Bangladesh.
Det.-Const. Karen Armstrong, of 41 Division, said he has been in Canada since 2008.
She alleges the suspect used his position of authority but stopped short of calling him a sexual predator.
Armstrong said it was a three-week investigation and police refused to reveal any information about court appearances.
The allegations deal with sexual related offences and threatening death.
Police said the suspect taught the Koran both at the mosque and privately at homes.
