The break-in occurred at about 10:30 p.m. Monday at the county-owned facility, which is located in a canyon about 10 miles west of Goleta, said Kelly Hoover, a Sheriff's Department spokeswoman.
The tools — valued at about $3,000 — were stored in a locked metal bin on the property, Hoover said.
Deputies responding to a burglar alarm found four suspects fleeing the area, Hoover said.
After a foot pursuit, two of the suspects — Marvin Palacios, 25, and Estiban Henriquez — were taken into custody.
A short time later, a third suspect, Rony Lopez, 36, was tracked down by a sheriff's K-9 unit, Hoover said, adding that the dog bit Lopez, causing minor injuries.
"Despite an extensive search by sheriff’s deputies, the sheriff’s K-9 unit and California Highway Patrol, the fourth suspect was not located," Hoover said.
All three suspects were charged with burglary, conspiracy and resisting arrest., Hoover said, and Lopez also was charged with attempting to injure a police dog.
They were booked into the Santa Barbara County Jail, with bail set at $20,000 each.
The stolen tools were recovered, Hoover said, and the search for the fourth suspect was continuing.
