CHENNAI: A man attacked his 55-year-old wife with a hammer near the Porur toll gate on Wednesday, leading to her death. The persons accompanying the woman then roughed up the husband, leaving him in a critical condition.

The police said that Raja (56) got enraged upon seeing his estranged wife, Sulochana (55), with her partner and struck her with a hammer. The incident occurred when he saw her while waiting to board a bus at the toll gate. According to the police, Sulochana succumbed to her injuries on Thursday.
