A 21-year-old University of San Francisco student was arrested on campus Thursday, Nov. 3, on child pornography charges, according to the San Francisco Police Department.

Sam Kerfoot was booked into the San Francisco County Jail on numerous felony charges including possession of more than 600 online child pornography images and attempts to seduce a minor.

Many of the images involved children under the age of three-years-old, according to authorities.

The SFPD Internet Crimes Against Children (ICAC) unit was alerted about Kerfoot's involvement with internet child porn in early September, according to police.
