Two armed men wearing dark hooded sweatshirts entered the bank at 8220 Old Redwood Highway around 5:55 p.m., police said.
The men demanded money and left with an undisclosed amount of cash. No one in the bank was injured, police said.
A witness later reported that three suspects pulled into a nearby apartment complex in the 200 block of East Cotati Avenue in a dark minivan, police said.
The witness said the men abandoned the minivan and left in a white, two-door Honda, possibly a Prelude, police said.
The Exchange Bank is offering a $25,000 reward for information leading to the arrest and convictions of the suspects.
