The Defence Ministry has denied that Defence Minister AK Antony's office was being bugged, saying an investigation into "inconsistencies" found during a routine sweep has turned up no proof of any bugging device. In a terse press release issued this afternoon, the government said, "Reports of 'bugging' in South Block in a section of the media is hereby denied. Routine checks are conducted in the offices of Raksha Mantri and other officers in South Block. Nothing has been found in these checks."
