The driver of the pickup truck that drove into the terraces of a brasserie and fast-food restaurant in the Belgian capital, Brussels, has been arrested.

This was reported by the Belgian news agency Belga on Friday, citing initially unnamed sources.

The driver was arrested in Antwerp.

Six people were slightly injured in the incident on Friday afternoon in Brussels.

The driver then fled.

It was initially unclear whether he intentionally or unintentionally steered the car into the terrace.

However, according to Brussels Mayor Philippe Close, testimonies could indicate a crime.

"What is certain is that the vehicle was traveling at extremely high speed and was heading for the terrace," the newspaper "Le Soir" quoted him as saying on its website.

The incident took place on Rue Saint-Michel, which is a side street off Brussels' well-known shopping street, Rue Neuve.
