Andhra police can be attributed corruption but communalism is not present amongst them. If someone visits Hyderabad, it can be easily noticed that people of all religions co-exist very well here. Not just Hindus and Muslims, Christians, Jains, Marwadis, Sikhs and a lot of other religions are in good numbers living happily in Hyderabad. This bomb blast is definitely a terror act I think directed from Pakistan so that the turmoil there can be overseen. The whole plan of terror failed as two other bombs didn't explode and peace stayed strong in Hyderabad.
