Over 200 French police officers have raided the notoriously rough Tarterets housing estate near Paris where two policemen had been ambushed and badly beaten up last week.
Reports say that police held at least nine people on the estate in Corbeil-Essonnes, which is just south of Paris, when youths hurled bottles at them and French Interior Minister Nicolas Sarkozy has vowed to catch "one by one" those responsible for the attack.
