SAN FRANCISCO (CBS SF) – San Francisco police have arrested five people on suspicion of child pornography-related offenses, police said on Tuesday.

Police said that last week, investigators arrested a pastor of a San Francisco Lutheran church on suspicion of possessing child pornography, possessing more than 600 files of child pornography and distribution of child pornography.

Police said investigators also found that Sabin had allegedly stored child pornography in a cloud storage application.

Late last month, investigators arrested 37-year-old San Francisco resident Trevor Schlesinger, who was allegedly uploading child pornography to a file-sharing network.
