Mangalore: A tunnel has been discovered in the Kollatupadavu of Niddoddi area in the Kallamundkoor village of Moodubidire taluk.

This tunnel is 13 feet deep from the earth’s surface. The tunnel is about 5 feet in side to the east. Within a short distance of the tunnel, there are large stones lying on it and  the route is likely to continue.. That being said, the water may have been naturally created for the flow of roughness.
