Ernakulam (Kerala): The Kerala Police on Tuesday detained three persons in connection with the brutal rape and murder of the 30-year-old law student here.
The incident has drawn parallels with the 2012 Nirbhaya gang-rape case of Delhi, as the dalit student in Kerala was meted out a similar brutal treatment.
Jisha was found lying dead in a pool of blood on April 28 at her home near a canal in Perumbavoor in Ernakulam by her mother who works as a casual labourer.
Her body was badly mutilated; there were injuries on her private parts, according to the police.
The police are waiting for forensic reports to find out if the victim was raped and then murdered.
"The suspect attacked and murdered her brutally and fled the scene quickly," said police inspector general Mahipal Yadav, who is heading the investigation into the case.
"There are indications that her intestines came out after severe violation by some foreign object," Yadav told AFP.
Kerala Home Minister Ramesh Chennithala said police had registered a case of rape and murder and detained three people for questioning.
"Police have booked a case of rape and murder... today three people were taken into custody for interrogation," AFP quoted the minister as saying.
"Police are working very hard on this case, we will bring all the culprits to book within no time. There will be no laxity."
Protesters staged a demonstration in state capital Thiruvananthapuram on Tuesday, many covering their mouths with black handkerchiefs and carrying placards demanding justice for the victim.
