A state police child pornography investigation led troopers to the sub base in Groton.
On January 7, police arrested Adam Simpson, 27, of Groton, and charged him with possession of child pornography.
State police began an investigation into Simpson in January 2013 after detectives noticed files suspected of being child pornography were being shared from his computer on the sub base.
Because Simpson is a member of the U.S. Navy, state police notified Naval Criminal Investigative Service (NCIS) and then executed a search and seizure warrant at Simpson's room on the base.
Investigators seized a laptop computer. Detectives found several child porn videos saved on it, according to court documents.
Simpson admitted to downloading child pornography, court documents revealed. He allegedly told police he was interested in girls 10-16 years of age. Simpson also said he used Skype and other video chat services to record young girls he had enticed into performing sex acts on camera, according to court documents.
He was arraigned on Jan. 8 and held on $150,000 bond.
