Naresh Tharu, 17, of Thakurbaba Municipality-3 collapsed and fell to the ground while playing a football match on Tuesday organised in the district on the occasion of Dashain and Tihar festivals, said Deputy Superintendent of Police Yubraj Khadka.

Scorching heat is suspected to be a reason behind him going unconscious. Investigations were underway to find the real reason though, Khadka added.
