On the night of Aug 14, Raksha Sharma was found hanging from the fan in a room of the hostel at the Mehar Chand Polytechnic here.
The names of Deepak Saini (21) and Lovepreet Singh (21) were mentioned in a note recovered from the computer engineering student's room. Both had graduated from the same institution earlier this year.
Raksha wrote in the note that the duo had posted obscene comments about her on the social networking site. Due to the humiliation, she felt uncomfortable facing her batchmates. Raksha stressed that the two of them should be punished for driving her to suicide.
Deepak and Lovepreet were taken into custody yesterday. Their computers were also seized. Police are planning to go through the duo's Facebook accounts.
According to Assistant Commissioner Balkar Singh, Lovepreet had sent offensive SMSes to Raksha when their friendship strained and even threatened to throw acid on her.
However, Luvepreet claimed innocence. "I haven't spoken to her in three months and she even considered me as her brother. I don't know how my name has come up in her note. I am ready for any investigation," he asserted.
On his part, Deepak admitted to posting the comments but pointed out that Raksha had not taken offence at that time. "I feel bad she killed herself but I am not responsible," he averred.
Meanwhile, the director of the SOS village in Jammu, where Raksha and her siblings had stayed after their parents were killed by militants in 1997, denied any knowledge of the accused having ever harassed her.
"We would speak to her very often and check about her studies, but she never mentioned this harassment to us. We are really shocked," said Prasanjeet Das.
