RAMBOUILLET, FRANCE (April 24): French police arrested three people linked to a 36-year-old Tunisian man who stabbed to death a police employee at her workplace southwest of Paris on Friday in a suspected Islamist attack.

The murder at a police station in Rambouillet, a commuter town about 60 kilometres (40 miles) from Paris, revived the trauma of a spate of deadly attacks last year.
