READING, Pa. (WPVI) -- Police in Berks County say an online file sharing service helped them catch a sexual predator.
Officers arrested Sean Michael Fager on child pornography charges at his Reading home on Thursday morning.
Police have been investigating the 49-year old since March.
That's when Dropbox first alerted them about content Fager was allegedly uploading to their site.
A search of his home turned up hundreds of images depicting children between the ages of one and five being abused.
