On December 11, police received a call regarding poisoning of an elderly couple at Janak Puri. After reaching the spot, the personnel shifted the unconscious couple to Deen Dayal Upadhyay Hospital, officials said.
During investigation, it was found that the couple had been given some unidentified substance by their recently-hired maid and that she was suspected to have ransacked the house and decamped with jewellery and cash, Deputy Commissioner of Police (West) Monika Bhardwaj said.

The police received information about the suspect and raids were conducted at Begusarai district in Bihar from where the accused was picked up, she said.
During interrogation, Reena confessed to the charges of the current as well as four other previous cases, Bhardwaj said.
In all these cases, Reena used to work in the houses of senior citizens and after two to three days of starting work she would poison them and decamp with valuables, she said.
Some gold jewellery and Rs 17,000 in cash was recovered from her, the DCP said.
