Malajun bin Mumin, from Pitas, died while waiting for his turn to see the doctor at about 3.20pm.
Prior to the incident, he complained of a headache when he and his 57-year-old colleague known as Bandasan were sending grocery items to a shop in Gaya Street.
Hence, Bandasan accompanied Malajun to see the doctor about his headache at a nearby clinic along the street.
However, before Malajun, who lived with his four children, could see the doctor, he fell on the floor and was later pronounced dead.
City Police Chief ACP Jauteh Dikun said police went to the scene after being alerted and the body was sent to the hospital for post mortem.
He said police have classified the case as a sudden death report.
