Investigators on Thursday claimed that the suicide notes they recovered from Geetika Sharma were written on the same day though they bore different dates.
After an analysis of the notes in which Geetika alleged harassment by former Haryana minister Gopal Kanda, police said they were written by the deceased on the same night she committed suicide.
There was some confusion after one of the notes had a May date while the other had August date.
Geetika had allegedly took her life on August 5 in her Ashok Vihar residence alleging that Kanda and his aide Aruna Chaddha were harassing her.
Investigators also said that Kanda denied all allegations against him and told them that he was not in touch with Geetika for at least 45 days before her suicide.
He also claimed that Chaddha, whom Geetika had named in her note, had called her parents on her own and asked her to join duty.
Police are also in touch with Ankita whose name also appeared in the note. She is out of the country and police expect to question her soon.
Another Kanda staffer Shivroop, who allegedly sent the forged emails to Geetika threatening her, was being questioned.
Police had yesterday said they were planning to slap a fresh charge of destruction of evidence against Kanda and question an actress Nupur Mehta who worked with the deceased in his firm.
