Three held after UK policeman stabbed to death

Three men were being questioned in the UK today after a police officer was stabbed to death and four others injured during a raid on terrorist suspects linked to last week’s discovery of the deadly poison ricin.

Forty-year-old Special Branch detective constable Stephen Oake died as three suspects of North African origin, aged 23, 27 and 29, were arrested yesterday afternoon at a flat in Crumpsall, north Manchester.
