"Police and bomb squad have carried out their search at Wipro campus and have found no suspicious object in the vicinity," a police officer told agency.
A letter claiming to blow up Wipro's corporate and training block at 11 AM on Friday and 1 PM on Saturday with 19 bombs was delivered to Sarjapur police station.
The letter had no mention about the sender, police said.
