Manju Monga, 58, was brutally killed by her husband Mukesh who attacked her with a knife while he was going to drop her at a boutique in Anand Niketan area where she worked, around 11.30 am, police said. A heavily drunk Mukesh Mongastabbed her nine times with a blunt knife in her throat, chest and eyes during an altercation between them over a phone call she received. The couple used to reside in Hari Nagar with their children, a 29-year-old son and a 30-year-old daughter. Mukesh, an alcoholic, told cops that he suspected Manju of infidelity as she received calls from her clients and an NGO with which she was currently associated. He was also livid that she sought an account of where he spent some money he had borrowed from her. However, neighbours told police that Mukesh was addicted to alcohol and that wasn't approved by Manju and he would also physically assault her, said the officer.  The bystanders who witnessed the incident rushed to the woman's help and caught hold of her husband behind Mount Carmel School in Anand Niketan area. A guard posted in the area later made a PCR call after which police reached the spot and arrested Mukesh. Children of the deceased told police that their mother was supporting the family and their father didn't have a permanent source of income.
