WHITEFISH BAY, Wis. (CBS 58) -- A teaching assistant at a Whitefish Bay childhood education program has been arrested for possession of child pornography. 

Whitefish Bay police say 21-year-old Nicholas Otero was arrested on Friday, April 4. 

Otero worked one day a week at Gan Ami Early Childhood, a program run by the Jewish Community Center. 

Program officials were told no pictures or videos discovered by police contain children or staff within their program.

In an email sent to families they say, "This is an extremely disturbing and serious issue that we take very seriously. the safety, security and well-being of the children in our care is our highest priority."

Gan Ami Early Childhood says the man passed multiple background checks and completed all mandated trainings. 

Otero is now suspended without pay.
