Adult trio charged over Annesley Collegel breakin One of Adelaide's most prestigious schools, Annesley College, was targeted in an alleged breakin. THREE people have been arrested after security guards allegedly found them rummaging through cupboards in a classroom at Annesley College early this morning. Guards were alerted when an alarm sounded at the Greenhill Rd school about 4.30am. Police said two men, 47, of Greenacres and 33, of Prospect, and a 38-year-old woman, of Kilburn, were detained by security until police arrived. The trio have been charged with breaking into the school and are all expected to appear in the Adelaide Magistrates Court at a later date. It appears nothing was stolen during the break-in, police said.
