The infected person had come from Iran through Bahrain, the report added.
The Kingdom's health ministry said it sent an infection control team immediately to check on the citizen, and to take a sample for laboratory examination, as part of its precautionary measures, according to Arab News.
The results confirmed the man was infected with COVID-19.
The ministry said it had ensured that the infected person remained isolated in hospital and is receiving medical treatment.
In addition, all those who contacted the infected person were counted, and samples were taken from them for examination by the National Center for Disease Prevention and Control.
Results will be announced once the examination is completed.
The ministry urged residents in the Kingdom to contact its hotline on 937 if they have any enquiries related to the virus.
