The suspect in the car-ramming incident at a Christmas market in the German city of Magdeburg had appeared in seven investigative proceedings in the two years prior to the attack, Germany's Frankfurter Allgemeine Zeitung newspaper reported on Saturday.

Four women and a 9-year-old boy were killed and 200 people were injured when a car was driven into the market teeming with holiday shoppers.

German prosecutors are commissioning a detailed mental evaluation of the suspected attacker behind a vehicle rampage through the crowded Magdeburg Christmas market that left five dead and more than 230 injured.

The number of people injured in the attack on a Christmas market in the German city of Magdeburg two weeks ago has risen to 299 from the previously reported 235, the state Interior Ministry said on Friday.
