PORTSMOUTH -- A Portsmouth man was arrested Saturday following a year-long investigation into the possession of internet child pornography.
Police arrested 34 year-old Derek Robert Hayley around 1:30 a.m. and executed a search warrant at his home in the 400 block of Bertha Lane.
Hayley is charged in a 20-count indictment for possession of child pornography.
According to police, evidence seized during the search warrant will be reviewed and additional interviews are forthcoming.
The case remains under investigation.
Hayley was convicted in 2003 for indecent liberties with a child by a custodian and in 2012 for failing to register as a sex offender.
