The incident occurred in evening when seven youths, all related to each other, were taking pictures in the river at K Gannavaram when they were swept away, apparently due to strong water currents, said Ramchandrapuram Circle Inspector P Kasi Viswanath.
He said the nearby fishermen pulled four out of the seven youths, all college students, to safety.
While body of Y Suman (20), a B.Tech student, was fished out of the river, search is still on to trace Y Pramila (20) and Y Praveen (20).
