OAKLAND -- Seventy police officers and FBI agents arrested several people and seized illegal assault weapons, ammunition and thousands of dollars' worth of heroin from a residence in West Oakland on Friday morning, authorities said.
Police said a recent spike in crime lead authorities to the area, but officers declined to say exactly where the raid occurred or how many people were arrested.
Police would only say they served "multiple search warrants" in a location near the Acorn housing projects in West Oakland.
Recovered were high-capacity ammunition magazines, raw tar heroin, cut heroin, and heroin packaged for sale with a street value of $30,000 to $50,000, as well as $1,600 in cash. Police also recovered illegal multi-round magazines, and a 100-round drum for an assault rifle.
The ammunition recovered included high-caliber and hollow-point bullets that can penetrate walls, car doors, and police body armor, police said.
The raid on Friday was the second time in just over a week that police have served warrants in that area. On the evening of April 24 and the early morning of April 25, more than 250 police and FBI agents served 16 search warrants around the East Bay, arresting five people and seizing guns and drugs.
Thirteen of the warrants served last week and all the arrests -- four adults and a juvenile -- were in the Acorn housing complex. The complex is bounded by 8th, 10th, Market and Adeline streets.
