African-Americans in San Francisco are stopped and searched by police officers in disproportionate numbers and are subject to a host of other actions that appear to be discriminatory, according to a report issued on Monday that found the Police Department was in need of significant overhaul. The report also said that the department’s disciplinary system was riddled with shortcomings.

San Francisco’s police force has been shaken by a series of scandals over the past two years, including racist and homophobic text messages exchanged by officers, cellphone videos of officers abusing residents, and questionable shootings of Latinos and African-Americans — including the fatal shooting in May of an unarmed black woman.

Gregory P. Suhr, the police chief, resigned under pressure in May, and the department is undergoing a review by the Justice Department’s Office of Community Oriented Policing Services. That review is separate from the city analysis released Monday.

The report, by the Blue Ribbon Panel on Transparency, Accountability and Fairness in Law Enforcement, found that while African-Americans make up 5.8 percent of the city’s residents, they constituted about 40 percent, 20 of 51, of the victims of officer-involved shootings from January 2010 through July 2015. (The study noted that no race was listed for suspects in 18 of the 69 total shootings during that period).
