The accused, Gurdas, who used to work as a safai karamchari at the shelter was arrested yesterday from Haridwar after his DNA matched with that of the aborted fetus of the victim, Dehradun SSP Sadanad Date said.
The accused who is already suspended by the Directorate of Social Welfare after his name cropped up as one of the suspects in connection with the case has been sent for 14 days in judicial custody, he said.
This is the ninth arrest in connection with the case in which eight others including the former superintendent of the shelter home and her deputy have already been arrested.
The arrest of Gurdas lends credence to the belief that shelter home insiders were involved in the sexual exploitation of the woman inmate who in her magisterial statement recorded with the help of a sign language expert earlier had accused several male employees of Nari Niketan of having perpetrated the crime on her.
