SACRAMENTO COUNTY, Calif. (KTXL) — On Friday, Sept. 2, the Sacramento County Sheriff’s Office and Sacramento Valley Hi-Tech Crimes Task Force arrested three Elk Grove residents on the suspicion of installing skimming devices on ATMs.

According to a news release from the sheriff’s office, Sorin Mitrache, 36, Marius Panciu ,43, and Papas Zacharias, 42, were arrested after a collaborative investigation with Bank of America Corporate Security.
