Heavily armed Oakland police officers raided three locations this morning including the Nation of Islam’s Your Black Muslim Bakery hours after it was reported that Oakland Post Editor Chauncey Bailey was investigating the group when he was gunned down by a masked man yesterday. Police would not say if the raids this morning were linked to Bailey’s murder. KTVU says officers used flash grenades as they entered the bakery and detained as many as 19 people. Police said a “small armory of weapons” was found inside. Police said the raids were part of a year-long probe into several violent crimes, including “murder, robbery and kidnapping.” Here’s the AP report. A news conference is planned later today.
