Nearly 1,700 suspected online child sex offenders were arrested in April and May, the Justice Department announced Tuesday.

The two-month operation, known as “Broken Heart,” was led by Internet Crimes Against Children task forces.

“Over the span of just two months, our ICAC task forces investigated more than 18,000 complaints of internet-related abuse and helped arrest 1,700 alleged abusers,” Attorney General William Barr said in a statement.

The task forces targeted alleged predators who produced, distributed, received, or possessed child pornography, engaged in child sex trafficking or online enticement of children for sexual purposes, or traveled across state lines or abroad to sexually abuse children.
