"Sanjay Sharma has submitted 60-70 page complaint today mainly alleging that Thakur misused his position as IG and both he and his wife possessed properties disproportionate to their known sources of income," a Lokayukta office source said.
Mehrotra, when contacted, said he has not yet seen the complaint in detail and would initiate further action only after its investigation.
Sharma said he has given the complaint on three points and requested for probe into the sources of income through which the couple bought massive properties.
"Their immovable properties should also be investigated," he said, adding he has also demanded a probe to see if any racket was going on through their NGOs since the woman who has levelled rape charges has claimed that she had been criminally assaulted on the promise of a job," he said.
"While Thakur claims transparency in public life in reality, he has double standards," Sharma added.
