- The 28-year-old's family has placed an ad in papers
- She left her Chennai home on Friday in her two-wheeler
- Her cell phone has been switched off since
"She was reportedly in depression. We are investigating," said a police source to NDTV on the condition of anonymity.
An online campaign by friends and family seeking information went viral on social media and was a Twitter trend this morning.
The 28-year-old, who works at a salon as a marketing manager, describes herself on Facebook as a photographer and "model at times". She lives with relatives; her father is based in Delhi and her mother died a few years ago.
Ms Nair left her house on Friday for work on her two-wheeler, but did not reach her office.
Her cell phone had been switched off since then.
On Facebook, Ms Nair used an account which identified her as Jikki Padhoo. In March, she posted a note about a lover: "A tear rolls down, from both our eyes, at the same time. My lips quivering, crying, I'm trying to prepare you, pulling myself up. But I give up the next minute. You slap me. You slap me crying, desperate, 'Get up Gaanam, get up."
"We understand she had marriage related issues with her family and had some health issues as well," said an investigator handling her case, to NDTV.
Another relative, who didn't want to be named, said, "I don't think she had any problem with the family."
