LAKEWOOD, Colo. — The Lakewood Police Department arrested a man on suspicion of possessing child pornography Thursday afternoon.

Joseph Scott Forrest, 49, allegedly had several pornographic images and one video of young girls stored on his Twitter account, according to LPD.

According to the arrest affidavit, Twitter removed the account when it received a report from the National Center for Missing and Endangered Children. An investigator obtained a search warrant and worked with Twitter to gain access to the explicit images Forrest allegedly posted on the social media site.

“We would like to thank Twitter and our partners at the National Center for Missing and Endangered Children for their assistance on this case,” a press release from LPD stated.

According to the affidavit, one Twitter image showed Forrest naked on his apartment deck. A black GMC pickup was seen in the background. Using that image, an investigator was able to confirm Forrest’s address.

The affidavit also stated that Forrest is a supervisor at Lookout Mountain Youth Detention Center in Golden.

The detention center sent the following statement to FOX31 and Channel 2:
