SUMTER, S.C. -- Two teenagers have been charged with assaulting a 14-year-old boy at Sumter High School earlier this year.

Police said Wednesday two 16-year-old boys had been charged with conspiracy and second degree criminal sexual conduct with a minor.

Authorities say a 14-year-old student told police in May that three people had assaulted him in a bathroom at the school several months earlier. The boy told police two people held him down while another penetrated him with a foreign object.

Bond was set for each defendant at $20,000, and it wasn’t immediately known if they had attorneys. Police said they were still working to identify a third subject.
