MACHILIPATNAM : The ACB officials on Saturday nabbed Guduru sub-inspector Adapa Krishna Mohan for accepting a bribe of `10,000 from a resident of Sanchala Koduru to register a case against his village sarpanch. A dispute erupted recently between K Gangadhar and village sarpanch Kolla Srinivas over fish ponds following which Gangadhar approached sub-inspector Krishna Mohan to lodge a complaint. However, the SI reportedly demanded `10,000 for taking action against the village sarpanch. With this, Gangadhar approached the ACB officials, who laid a trap and caught him red-handedly while he was accepting the amount.
