Hello Amgen,

There is no college in Bangalore who provides the B.A in criminology. There are some colleges in Karnataka which are listed below.

CM Managuli Arts and Science College

Government College Mandya - GCM

Maharaja Madakarinayaka First Grade College - MM

School of Social Work Roshini Nilaya - Autonomous

Shree Siddeshwar Government First Grade College

You can go for these colleges as they are in Karnataka only. 

Good luck.
