Delhi Police investigating the Sunanda Pushkar death case on Thursday said it may question Pakistani journalist Mehr Tarar over whom she fought with her husband Shashi Tharoor before her death last year. Delhi Police Commissioner BS Bassi said Tarar may be questioned, if required, as she may throw light in the case. "If required, we will speak to her as she is a relevant person who can throw light in the case. Our efforts will be to talk to her," Bassi said when asked whether the SIT probing the case will examine her.
