Kenyan police have detained four more people for questioning over the murder of a Catholic missionary in the east African country, a police spokesperson said Tuesday. “We have so far received very important information that I am confident will sustain a strong case against the suspects,” said Robert Kitur, assistant commissioner of police, according to Reuters. On Friday, police arrested two men in connection with the murder of Italian Bishop Luigi Locati last week. According to the Rev. Julien Kabore, the 76-year-old bishop was fatally wounded Thursday evening as he was walking to a pastoral centre in Isiolo, in the country’s north, where he was based.
