Separately, police have also arrested four people in an anti-terror probe in the town of Trappes west of Paris, the prosecutors' office said. It said those arrests were unrelated to the weapons probe, but gave no additional details. Arrests in the weapons investigation started Monday, with more on Tuesday and Wednesday morning, the prosecutors' office said. Coulibaly was an associate of brothers Cherif and Said Kouachi, who killed 12 at Charlie Hebdo's Paris office and also were killed in a shootout. The arrests come amid heightened security to protect the French presidential election ahead of the second round of voting May 7.
