A spokeswoman for the Berlin police said Monday that four more people had reported slight injuries after a man drove his Volkswagen Polo Sunday afternoon through security barriers near the Brandenburg Gate and into the crowd.

Twenty other adults had minor wounds while an 11-year-old boy suffered a concussion.

The driver, a 33-year-old German of Indian origin, was arrested at gunpoint after his car crashed into a fence in front of a stage set up for a classical music concert that evening at the central Berlin landmark.

He is facing charges of attempted homicide.

A 55-year-old woman in the passenger seat was also detained but later released.

Witnesses said he was driving about 50 kilometres/hour (30 miles/hour) and appeared to have intentionally careered into the crowd.

The Fan Mile stretching down the long boulevard behind the Brandenburg Gate has attracted hundreds of thousands of football fans for each of the World Cup matches broadcast on giant screens. But the crowd was thinner Sunday because no game was on.

After the incident, police evacuated a part of the Fan Mile as well as surrounding buildings while they searched the car for explosives. None were found.

The Fan Mile was expanded due to its enormous popularity and some 900,000 people are expected for the Germany v Italy semifinal Tuesday.
