PHOENIX (AP) -- Maricopa County Sheriff Joe Arpaio says he plans to launch his 20th crime and immigration sweep in Phoenix in the near future.

The sheriff's office wouldn't specify the date of the special immigration patrols.

During the sweeps, deputies flood an area of a city to seek out traffic violators and arrest other violators.

Critics say Arpaio's deputies have racially profiled Hispanics during the sweeps.

The sheriff says deputies approach people only when they have probable cause to believe people had committed crimes.
