OAKLAND -- The names of 13 reputed members of a violent East Oakland street gang arrested recently as a result of Operation Ceasefire and the charges filed against them were released by authorities Tuesday.

Two of those arrested and charged -- Frederick Manning and Shawn Hampton -- were identified by police as leaders of the Money Team gang.

The 13 were arrested Aug. 15 and Aug. 22 in raids led by Oakland police that were carried out in East Oakland, Hayward, Fremont and Antioch.

Besides Manning and Hampton, also arrested were: Kenneth D. Denson, Joevonne Damario Ralls, Briana Thrower, Marvin L. Matthews,, Abraham Buffin, James E. Gates, Lamar R. Buffin, Joseph Brown, Denzel Jones, Brian L. Clark and James Davis..

All either live in Oakland or have ties to the city.

The Alameda County District Attorney's Office so far has charged the 13 with 21 felony counts, including conspiracy to commit a crime, kidnapping to commit another crime, street terrorism, second-degree robbery and first-degree residential burglary.

The alleged crimes occurred in different parts of Oakland between June 27 and Aug. 4. Not all the suspects are charged with the same crimes.

The gang was a Ceasefire target because they are believed responsible for numerous killings, shootings, armed robberies and home-invasion robberies. Some victims were members of other gangs, including another East Oakland gang known as Case Boys.

Under Ceasefire, which is Interim Chief Sean Whent's main crime-fighting strategy, members of the gang or their representatives were told by police that unless they stop the violence and change their lifestyles they would be arrested.

The names of those arrested were not immediately released by police, who cited a section of the state Government Code that allows them to withhold the names for a period of time. A portion of the section states that the information can be withheld if "it would endanger the safety of a person involved in an investigation or would endanger the successful completion of the investigation or a related investigation."

Officer Johnna Watson said some considerations when withholding names include situations in which police are still seeking suspects, and when there is the possibility of retaliation against those arrested and their family members by rival gangs or victims of their crimes.
