A series of serious road collisions spanning Europe, Asia and South America has left at least one person dead and multiple others hospitalised, with drivers in Italy and Hong Kong taken into custody. In Milan, a 37-year-old Ukrainian national was arrested after his Mercedes struck a motorcyclist and a pedestrian at an intersection in the east of the city around midnight, according to Italian news agencies. The motorcyclist is fighting for his life in hospital, while the pedestrian sustained less severe injuries. Local police said the driver failed to yield, fled the scene without rendering aid, and was later stopped on the northern ring road, where a breath test recorded a blood-alcohol level of 0.91 g/L — above the Italian legal limit.

In Hong Kong, police arrested a 74-year-old minibus driver for dangerous driving causing death after a collision in Ta Kwu Ling early Friday morning. The South China Morning Post reported that the minibus was travelling along Man Kam To Road towards Sheung Shui when it struck a cyclist near Hung Kiu San Tsuen. Emergency services found the cyclist unconscious with severe head injuries; he was pronounced dead at North District Hospital shortly before 7 a.m. A 43-year-old female passenger in the minibus complained of waist pain and was also hospitalised. The driver was detained for questioning and subsequently arrested.

Swedish authorities have opened a preliminary investigation into gross negligence in traffic and gross unlawful driving after a motorcyclist in his mid-30s was seriously injured in Färgelanda on Thursday evening. According to Sveriges Television, the man lost control and left the road south of Ödeborg for reasons that remain unclear. He was airlifted to hospital, and the motorcycle has been seized for a technical examination. In Argentina, a collision between a car and a motorcycle at the intersection of 121 and 38 streets in La Plata on Thursday afternoon sent two riders to hospital. Local media reported that residents blame a large pothole at the junction, which they say forces drivers to swerve into oncoming traffic. Police at the scene confirmed the car lacked mandatory third-party insurance, a violation that complicates compensation for the injured.

All four incidents remain under active investigation. In Milan, the driver faces charges of failure to render assistance and causing very serious injury. Hong Kong police are continuing their inquiry into the fatal minibus crash. Swedish prosecutors await the results of the technical analysis of the motorcycle, while Argentine authorities have ordered a scientific police examination to determine the precise mechanics of the La Plata collision.
