The driver passed two barriers before hitting one of the southern entrances to this most sacred site in Islam.
Authorities said the man, who appeared to be in "abnormal condition", was brought before a prosecutor to face possible charges.
A Saudi man drove into Mecca's Grand Mosque and struck one of the entrances to Islam's most sacred site in western Saudi Arabia, authorities said on Saturday.
Guards rushed at the driver whose car passed two barriers before hitting one of the mosque's southern entrances on Friday, according to holy city officials and videos on social media.
Authorities did not identify the man but said he appeared to be in "abnormal condition".
He was referred to a prosecutor to respond to possible charges, they added without providing further details, including the causes of this incident.
Seven month break
In early October, Saudi Arabia allowed worshipers to pray in the Grand Mosque after a seven-month hiatus due to the Covid-19 pandemic and allowed 15,000 Muslims to make the small pilgrimage to La Mecca, Umrah.
Umrah, which can be undertaken at any time of the year, had been suspended in March due to the pandemic.
Saudi Arabia organized the very limited annual pilgrimage to Mecca (hajj) at the end of July.
Only 10,000 Muslims residing in the country were allowed to participate, far from the 2.5 million people who performed this rite in 2019.
