This marks the third casualty from the blasts at the convention centre.
Two women who were part of the gathering had lost their lives on Sunday.
Over 50 individuals were injured, some seriously, during the multiple blasts at the international convention centre in Kalamassery where the followers from the minority Christian group, Jehovah's Witnesses, had gathered for the final day of a three-day-long prayer meeting.
A few hours after the incident, a man claiming to be a member of Jehovah's Witnesses, surrendered before police in Thrissur district of the state, saying that he carried out the multiple blasts.
