According to news reports, the suspect was caught by police officials two days back. The suspect is said to have confessed to his crime later. He was caught at the Palakkad border and is now being questioned by police officials.
Police officials however, are waiting for DNA results of the suspect to check whether they match the saliva and blood samples found on the victim's body before making any official confirmation on his arrest.
The suspect is a migrant worker from Assam.
Meanwhile, Kerala chief minister Pinarayi Vijayan on Thursday said: "One suspect has been taken into police custody in connection with the Kerala student rape and murder case." ""This is certainly going to be a feather in the cap of the police probe team," Vijayan told reporters.
The case gained national spotlight after several criticised the officials for not making a headway into the investigation. Vijayan, who came to power recently, assured a fast investigation and trial in the case.
The incident also threw light on the law and order situation and the safety of women in the state. The victim, who was a law student, lived with her mother. On 28 April, she was allegedly raped before being murdered in her home.
