According to a government order issued on Wednesday it was done after an adverse report was received from the Director General of Police.
There have been demands from various political parties and others to ban the FOP as their members were allegedly used by the police in Sathankulam in Tuticorin district in assaulting P. Jeyaraj and his son J. Bennicks, resulting in their custodial death in June.
The Central Bureau of India (CBI) has since taken over the probe into the custodial deaths.
