A 16-year-old youth has been arrested after a 19-year-old man was shot dead while gardening in Schiedam. The victim was attacked by three people as he tended the front garden of a house in Weverpad with two other people on Saturday afternoon. Both his companions were wounded in the incident, but their injuries are not life-threatening. One was taken to hospital for treatment, while the other suffered minor injuries and fled the scene.
