Two Petaluma teens were arrested early Wednesday after police responding to a burglary alarm found them inside a classroom at San Antonio High Continuation School on the west side of Petaluma, authorities said.

The suspects, age 16 and 17, appeared to be stealing property from the Vallejo Street school, including a boombox, when police found them inside the classoom shortly before 1 a.m., Sgt. Ed Crosby said.

There were signs the pair had entered through a window, Crosby said.

Both teens were arrested for suspected burglary and booked into Sonoma County Juvenile Hall, Crosby said.

There names were not released because they are juveniles.
