Police say the young girl identified the security guard in a field line-up. Along with a police investigation, the school is conducting an internal investigation of its own.

"It would entail speaking with the employee and speaking with those involved, and then at that point deciding what next steps need to be taken," said Keith Hayashi, complex area superintendent.

The alleged assailant has been the school's security guard for five years. He's one of two guards there.

Right now the security guard is on paid leave until the school finishes its investigation.
