Additional Sessions Judge Sunil Kumar Aggarwal released the man, a resident of Rohini in northwest Delhi, after directing him to furnish a personal bond of Rs 50,000.
"No plausible reason has been offered for not specifying the rape incidents of December 2, 2015 and December 5, 2015 to the police on being called on December 10, 2015. Further delay of about one month therefrom in the registration of the FIR is crucial but unexplained," the court said, adding that the man was no more required for investigation.
He also argued that the victim had refused to undergo medical examination.
According to the complainant, she was raped twice when she went to clean her landlord's house who was also residing in the same building.
She had alleged that he had locked her up and threatened to kill her if she disclosed the incident to anyone. An FIR was registered in the case on January 13 this year.
