All but 20 of the 157 registered sex offenders in Fairfield were contacted in person or by phone during a registration compliance sweep on Friday, a police lieutenant said.
Seven of the registered sex offenders gave a false address or moved without giving police their new address, and warrants were issued for their arrest, Lt. Greg Hurlbut said.
Two other registered offenders were in custody on unrelated charges in different jurisdictions, Hurlbut said.
Fairfield police usually conduct registration compliance sweeps every three or four months, but other law enforcement issues delayed the sweeps for the past year, Hurlbut said.
Twenty officers participated in the three-hour sweep throughout the city, Hurlbut said.
California Penal Code 290 requires convicted sex offenders to register with local law enforcement agencies.
