Gujarati Businessman Ashok Shah and his wife were Murdered at their residence in South Kolkata

Businessman Ashok Shah and his wife Rashmita Shah were found dead on Monday at their flat in Harish Mukherjee Road, which is considered to be a high-security zone because of its proximity to CM Mamata Banerjee's residence.

The murder of the Gujarati couple might have links to the stock market, and the killings could have been executed by someone close to them, police said. The couple had significant investments in the share market, they said.

Gold jewelry and several cash have been reported missing from the house. Due to the non-functional CCTVs of that particular area police could not get the information about the murderer.

The couple was killed around 3 p.m on Monday according to the post-mortem examination reports, the officer said.
