Ventura police say they caught four teenage boys breaking into Balboa Middle School Sunday evening.
Around 6:18 PM, they received a 911 call from an alert citizen who spotted the teens breaking into the office at the school in the 200 block of South Hill Road.
The caller kept the dispatcher updated as to what was happening and when officers arrived on the scene they caught and detained the four teens.
A 17-year-old suspect was arrested for vandalism because he is alleged to have used a permanent marker to write graffiti on several locations and office doors.
A 16-year-old suspect was arrested for allegedly being in possession of alcohol.
Police say the other two 16-year-olds were released without charges.
They are asking the public to be extra watchful around school campus while they are closed for the summer and report anything suspicious.
Also, Ventura has a Graffiti Removal Hotline (805) 654-7805.
