Bryan Herrera - Repeat Sex Offender

A former Anchorage police officer, already convicted once of possessing child pornography, has been arrested and charged again.

Bryan Herrera, 44, was charged last month with violating the terms of his probation for having downloaded and stored thousands of child porn images in his computer, according to police spokeswoman Marlene Lammers.

On Wednesday, the Anchorage Police Department's Cyber Crimes Unit detectives re-arrested Herrera on a new charge of child porn possession. He is being held on that charge in lieu of $30,000 bail, Lammers said.

A 12-year veteran at the time, Herrera was charged in October 2005 with collecting images of young children having sex with each other and with adults.He was also accused of setting up a remote-controlled camera in his home so he could tape a teenage girl undressing.

In a plea agreement with the district attorney's office, Herrera pleaded no contest to two counts and was sentenced to serve up to two years in prison. He was released on probation after serving his time. A condition of his release was that he not have a computer with an Internet connection.

In June, probation officers told police they had seized Herrera's laptop and believed he had downloaded and stored child porn on it. Police forensics computer examiners verified the accusation and on Dec. 10 probation officers arrested him, according to Lammers.
