A WORRIED husband raised the alarm that his wife, a PhD student at the University of Tasmania, had gone missing, police said yesterday.
Natasha Narang, 30, of Mowbray, was last seen in that suburb on Friday about 1.45pm in Plumer Street.
Police are concerned about the disappearance which stretched into its third day yesterday.
"We are concerned in that it is unusual for her to have gone missing and we can't make contact with her," Launceston police Inspector Michael Johnson said.
"We are not concerned in the sense we suspect anything adverse [has happened]."
Inspector Johnson said there was no indication of any foul play at this stage.
Ms Narang lives with her husband but has no other family in Australia, police said.
Inspector Johnson said police had received information since the alarm was raised but it had not proved fruitful. She is described as being about 165 centimetres, of medium build with long black hair.
She has olive skin and is of Indian descent.
She was last seen wearing a long sleeved black top, grey coloured jeans and black shoes.
Police would like anyone with information in relation to the whereabouts of Ms Narang to contact either Crime Stoppers on 1800 333 000 or Launceston Uniform on 6336 3945.
