AP police is doing a very good job. The investigation should not be handed over to CBI. It is fact that CBI has become the extended arm of the ruling party. Court strictures against CBI on various occasions has proved it. With centre having a very bias & soft corner for muslims, CBI is bound to slow down the investigation ultimately leading to no conclusion. If AP Govt want peace, it should screen and throw out all illegal emigrants from Bangladesh, Pakistan etc.
