A Mohali hotelier shot dead his wife following an altercation at Phase X here on Wednesday morning.
The couple was travelling in a car when following a heated exchange, 60-year-old Nirankar Singh Sarao fired at least six shots at his wife, Kulwant Kaur, 62, from point blank range, leaving her dead on the spot.
Nirankar has been arrested and the gun used in the crime recovered.
Nirankar was undergoing heart treatment at the PGI, Chandigarh, for which he, along with his wife, had left his Hotel Sarao in Phase X, where they were staying, around 9.30 am.
They left in the hotel manager's Tata Indigo car after leaving behind their own Mercedes with the manager for service.
Neighbour Jasmeet Singh said the couple looked fine when they met him before leaving the hotel. It was around a kilometre away that Nirankar stopped the car near a private school and following a heated argument, he fired from his .32-bore revolver, leaving his wife dead in a pool of blood.
A passerby informed a PCR team, which rushed to the spot and took Nirankar in custody and recovered the weapon and the vehicle. The body was sent to the civil hospital for post-mortem.
A murder case has been registered against Nirankar at the Phase XI police station.
The couple has two children, both settled in the UK.
