The total number of people arrested for being involved in three weeks of rioting that seared France has climbed to more than 4,700, following the arrest of 1,540 people in the wake of the unrest, interior minister Nicolas Sarkozy said Thursday. "Arrests didn't stop with the end of the riots," he told a gathering of mayors. "Those who pillaged, those who behaved as delinquents have debts to pay to the courts in our country," he said. Sarkozy did not say how many of those arrested remained in custody, nor how many would face criminal charges. The last figures from the national police service, the DGPN, showed that 650 have been jailed.Sarkozy, who was vilified by many of the youths taking part in the riots, maintained a hard line throughout the crisis, ordering vigorous police action and deporting some non-French citizens who participated. The latter measure has generated controversy because of the high-immigrant nature of the suburbs involved. Though most of the youths taking part were French citizens, born in France, many have north and west African origins, and the DGPN said six to eight percent were not French nationals. According to surveys, Sarkozy's tough approach has won the approval of the majority of French voters, on whom he is counting to realise his ambition of replacing Jacques Chirac as president in the 2007 elections.
