Neighbours generally come to each other's aid, but a woman recently helped herself to the money and valuables of another resident in her building. The Mumbai Crime Branch's unit-XI arrested the woman, Ruchita Sachin Tanna, 38, for robbing a senior citizen's house at Charkop, on Wednesday.

Akbar Pathan, DCP detection, said, "Tanna stays in the same building as the complainant. She and the complainant regularly workout at the gym in their building. During the workout every body keeps their belongings in a corner. On June 20, Tanna stole the house key from the victim's purse kept there and entered her flat."
