Ratan Tata, the chairman emeritus of one of India’s biggest conglomerates, Tata Sons, is in critical condition and in intensive care in a Mumbai hospital, two sources said on Wednesday.

Tata, 86, said on Monday he was undergoing routine medical investigations due to his age and related medical conditions.

A representative for Tata did not immediately respond to a request for an update on his condition on Wednesday.
