Dumor died on 18 January 2014 in his London home after a cardiac arrest, having been on air the day before. President of Ghana John Mahama said in a message on Twitter that Dumor was one of Ghana's "finest ambassadors" and "was a broadcaster of exceptional quality and Ghana's gift to the World."
On 3 February 2014 Komla Dumor's body was flown back to Ghana, where it was received at Kotoka International Airport by a group of family members, friends, government officials, sympathizers and members of the Aflao traditional council, who also performed some traditional rites, since Aflao was his hometown. Funeral ceremonies for Dumor were held from 21 to 23 February 2014 in Accra.
