Police detained a 19-year-old man and 14-year-old girl after they sneaked into a Bixby Knolls school to steal classroom supplies Sunday evening, according to authorities.

The teenagers got in through an open window at Hughes Middle School and took a projector and several calculators before a school safety officer stopped them around 7:25 p.m., LBPD spokeswoman Shaunna Dandoy said.

The safety officer called in police, who arrested the 19-year-old, Dandoy said. Authorities identified him as Tyler Strauss, a Compton resident, who was booked into jail on suspicion of commercial burglary and held on $20,000 bail.

The girl was booked on suspicion of burglary and resisting an officer before being released to her family, Dandoy said.

Police said they recovered the stolen items.
