Vivo India directors Zhengshen Ou and Zhang Jie left the country as the Enforcement Directorate intensified its inquiry into the money laundering case against the Chinese firm, said sources.
The information comes a day after the agency carried out searches at 40 locations in connection with the case.
The federal agency on Tuesday conducted searches at 40 locations in Uttar Pradesh, Madhya Pradesh, and some southern states in connection with a case linked to Vivo Mobile Communications and some other Chinese firms.
The case is already being investigated by the Central Bureau of Investigation (CBI).
