Gurugram, Oct 14 (IANS): The wife of an Additional District Judge in Haryana, who was shot at by her husband's Haryana Police security guard on Saturday, succumbed to her injuries in a hospital, police said on Sunday.

Ritu, 38, died overnight, forensic expert and doctor Deepak Mathur told IANS.

The judge's son Dhruv, 18, who too was shot at, was very critical and admitted in a private hospital.

Haryana Police Constable Mahipal Singh, who fired the shots, hailed from Mahindargarh and was attached to the judge, Shrikant, for nearly two years.
