NANTES, France – An explosion early Sunday damaged the door and some windows of a business school that had been headed by a man recently appointed France's first prefect of Muslim origin -- whose car was bombed a week ago.
Police immediately cordoned off the area around the Audencia (search) school and opened an investigation.
Four days later, his car, parked on a street near his home, was blown up.
Dermouche's appointment was a major event in France, which is struggling to integrate its Muslim citizens, a population estimated at some 5 million -- the largest in Western Europe.
Investigators are still trying to ascertain who blew up Dermouche's car. They explored the possibility of personal revenge, detaining three people connected to Dermouche's ex-wife. However, the three were released on Thursday.
Sunday's 6:15 a.m. blast damaged the door and broke some windows at the Audencia school.
Ziad Khoury, a deputy prefect of the Loire Atlantique, the western France region where Nantes is located, said that there apparently were no witnesses to the explosion at Audencia, a well-known business school headed by Dermouche until he was named a prefect.
