The incident took place in front of the couple's seven-year-old son. After his father fled from the spot, he alerted a pedestrian who called the police. Upon reaching the scene, a team from Byculla police rushed her to the hospital. However, she could not be saved and succumbed to injuries.
"We registered a case of murder and began hunting for the accused. We suspected that he could flee to his native place. Accordingly, we placed our men at nearby railway stations premises in plain clothes. He was later arrested in the evening near Dockyard Road railway station when he came to board a train," said Ashok Khot, senior inspector at the Byculla police station.
The accused will be produced before the court on Thursday.
