A man drove his car into pedestrians in the northern Italian city of Modena on Saturday, injuring eight people, four seriously, officials said. They included a woman who had to have both her legs amputated. After the car came to a halt against a shop window, the driver emerged holding a knife and injured a passer-by who gave chase, before the suspect was overpowered. The suspect, 31, has been identified by officials as an Italian national of Moroccan origin. Italy's Prime Minister Giorgia Meloni, who cancelled a planned trip to Cyprus and described the incident as extremely serious, visited the injured in hospital with President Sergio Mattarella on Sunday. She also met Luca Signorelli, the passer-by who intervened, and thanked him for his actions. What makes an ordinary person heroic is the moment when the heart chooses to do good, even when that involves a risk, she wrote on X, sharing an image of their embrace. The incident occurred around 16:30 (14:30 GMT), when the speeding car hit the pedestrians in Via Emilia next to the iconic cathedral of Modena, south-east of Milan. The vehicle then veered left before coming to a halt against a shop window. Signorelli had told Italian media he was trying to help the woman when he noticed the driver trying to run away. He said he gave chase and the attacker turned on him with a knife in hand. He received a blow to the head and one on his chest before being able to restrain the suspect, with help from other passers-by. At a news conference on Saturday evening, the prefect of Modena Fabrizia Triolo said the suspect had been referred to a mental health centre in 2022 for schizoid disorders, but had then disappeared without a trace. Witnesses described the car approaching the kerb at high speed, estimating it was going at least 100 km/h (62 mph) and stated, We saw people flying. Modena's Mayor Massimo Mezzetti noted that it appeared the driver deliberately drove onto the pavement, hitting several people and crashing into a shop window before brandishing a knife. Among the injured were five women and three men. The driver was born in Bergamo and lived in Modena. He has been named as Salim El Koudri by Italy's far-right Deputy Prime Minister Matteo Salvini, who described him as a second-generation criminal; however, Italian media reported he is unemployed and has no criminal record.
