Jacob Thomas, a retired IPS officer in Kerala, has joined BJP by accepting the membership from party's national president J P Nadda in Thrissur on Thursday.
Thomas who retired in the rank of director-general police faced several allegations and was also under suspension for several months after he published a service story flouting norms and also flayed the government in the open.
BJP Kerala president K Surendran said that it is owing to rampant corruption in Congress and CPM led fronts that led Thomas to join BJP.
