Narco test on Aftab Amin Poonawala, accused of murdering his live-in partner Shraddha Walkar, is likely to be conducted on Thursday, sources said.

The 28-year-old will, however, have to undergo a set of tests to ascertain his emotional, mental, physiological and psychological well-being. The narco analysis cannot be conducted if he is found to be "disturbed" in the preliminary tests.
