Police and other local law agencies did a sweep Tuesday to see if registered sex offenders in Mountain View are in compliance with registration requirements. The effort led to the arrest of one person, not registered as a sex offender, for an unrelated warrant offense.

Officers visited 48 registered sex offenders at their residences across Mountain View Nov. 18. During the visits, one person was issued a citation and another was arrested, according to a press release by the sheriff's office. Both people had outstanding warrants.

There are a total of 60 registered sex offenders in Mountain View, according to the Santa Clara County Sheriff's office.

Law enforcement agencies that took part in the effort include the Mountain View police, along with the county's Sexual Assault Felony Enforcement (SAFE) Task Force, the Milpitas Police Department and the Santa Clara Police Department.

Compliance sex offender laws, among other things, requires people convicted of some sex offenses to register as a sex offender with the police, and update that information annually. The public disclosure does not necessarily mean the sex offender will show up on the Megan's Law database.

The SAFE Task Force also monitors sex offenders who have a "high propensity" to commit another sexual offense, and both tracks and apprehends sexual predators.
