Inspector-general of police Khalid Abu Bakar was barred from the probe into the controversial protest against a Taman Medan Church on April 19, said the Home Ministry.
"In the recent Church protest at Taman Medan, as one of the participants is the IGP's brother, the management of the Royal Malaysian Police (PDRM) decided that any matters relating to this case will be handled by the deputy inspector-general of police.
"This is to avoid unfairness in the investigation," it said in a parliamentary written reply.
