Jeremy Bailey, 28, Frederick Routt, 39, and Christopher Bauman, 36, were all arrested and charged with commercial burglary.
Meanwhile, 36-year-old John Martinez will be charged at a later date. He's currently in custody in Madera for theft of copper wire.
Investigators say the suspects burglarized several Merced businesses, stealing copper for resale. The damage to those buildings is more than $250-thousand.
