Officers responded at 12:59 p.m. to a robbery that had just occurred at the Bank of America in Roseville Square.
A man armed with a butcher knife approached a clerk and presented a note demanding money, according to a Roseville Police Department news release. The clerk gave the man an undisclosed amount of cash, and he left the bank. No injuries were reported.
Witnesses described the robber and an unshaven white male with a blond goatee, wearing a gray, hooded sweatshirt and dark shorts.
A few minutes later, a Roseville officer spotted a man matching the suspect's description at a gas station at the corner of Douglas and Sierra College boulevards. They took him and a suspected accomplice into custody without incident.
