Police in Malmö are aiming  to crack down on a recent wave of gun crime in the city. Violence in Sweden's third largest urban centre has escalated in the past two months, including shootings, explosions, hand grenades being thrown and cars and buildings set on fire. On Friday night a man in his twenties was shot in the street in the nearby town of Arlöv and on Thursday a 25-year-old man was in hospital after being shot in Malmö. Regional police put the rising violence down to an increased import of illegal weapons and are calling for tougher border controls on the Öresund bridge between Sweden and Denmark in a bid to tackle the problem.
