Santa Monica College investigates why a 4-year-old girl was pepper-sprayed

A California college announced Wednesday that it will launch an investigation into a pepper spray incident that left two people hospitalized, several people injured and a 4-year-old girl sprayed, according to a statement obtained by The Santa Monica Dispatch.

Approximately 100 students protested outside the Santa Monica College's Board of Trustees meeting against a plan of higher priced summer classes for the school, chanting "Let us in" and "No cuts, no fees."

Campus police tried to prevent protesters from disturbing a public comment period when pepper spray was released into the crowd. Police are investigating into who released the pepper spray and when.

"Santa Monica College regrets that a group of people chose to disrupt a public meeting in an unlawful manner," college president Chi Tsang said in a statement. "The college has launched a full investigation into the matter."

Santa Monica Campus police public information officer Bruce Smith said his department "wouldn't be able to comment beyond" Tsang's initial statement at this time.

The college said it would reimburse any injured student for his or her medical bills.
