Three calls made by unidentified persons stating that bombs were planted at petrol pumps and would explode any time kept the policemen on tenterhooks on Tuesday. However, these calls turned out to be hoax.

Miscreants called City and Cyberabad police control rooms between 8.30 a.m. and 10.30 a.m. to inform that bombs were planted at three petrol pumps in Santoshnagar Crossroads, Attapur and Rajendranagar. Bomb disposal squads were rushed to these spots and examined surrounding areas for more than one hour and declared them to be safe.

Senior officials said the efforts were on to trace the callers.
