Former Haryana minister Gopal Kanda, who is accused of abetting the suicide of his former employee Geetika Sharma, remained elusive for the fourth day on Saturday.
Raids were conducted in several parts of Delhi, Haryana and Siliguri to trace Kanda but the efforts proved futile, a senior police official said.
Geetika Sharma, 23, a former air hostess with Kanda's now defunct MDLR airline, was found hanging in her flat in Delhi on Sunday.
In a suicide note found at her residence, Geetika alleged she was ending her life due to harassment by Kanda and MDLR official Aruna Chaddha. Both Kanda and Aruna have denied the allegations.
The official said they have questioned one of Kanda's relatives to find out the whereabouts of the former minister.
Meanwhile, a Delhi court on Saturday extended the police custody of Chaddha by a day to recover certain crucial documents pertaining to the deceased.
Metropolitan Magistrate Manish Khurana allowed the custodial interrogation of Chaddha till Sunday after police said the documents of an educational society formed by the MDLR group are yet to be recovered and Geetika was the resident of that society.
"Considering the facts and circumstances of the case and the nature of offence and the fact that the police investigation could not be completed because of a holiday (Janmashtami), I am of the considered view that the police remand of the accused is necessary for the purpose of investigation," the court said.
Advocate B S Rana, who appeared for Chaddha, opposed the plea, saying she had been in police custody for the past three days. But the police told the court that she was not cooperating.
