UPDATE:  ATLANTA (AP) - The FBI says 169 people were arrested as a result of an 11-day effort targeting human trafficking in the lead-up to the Super Bowl in Atlanta.

The FBI says in a news release Tuesday that the operation ran from Jan. 23 through Feb. 2. The FBI says it aimed to raise awareness by taking proactive steps to address the threat of sex trafficking before and during the Super Bowl.

The FBI says the arrests included 26 alleged traffickers and 34 people accused of trying to have sex with minors. The agency says nine juvenile sex-trafficking victims were recovered, and nine adult human trafficking victims were identified.

The FBI collaborated with more than two dozen local, state and federal law enforcement agencies and prosecutors' offices, as well as non-government organizations.

PREVIOUS STORY: ATLANTA (AP) - Authorities say 33 people have been arrested in Atlanta on sex trafficking charges ahead of the Super Bowl.

Homeland Security Investigations Agent Nick Annan tells The Atlanta Journal-Constitution that the arrests happened this week, but declined to discuss case specifics due to ongoing investigations.

Authorities say four victims have already been rescued. Advocates for sex trafficking victims say sex traffickers are attracted to large sporting events, such as this Sunday's game between the Los Angeles Rams and New England Patriots.

Douglasville police say 16 people were arrested last week as part of an undercover operation whose timing was related to the Super Bowl. Atlanta police Chief Erika Shields says planning for Super Bowl security began over two years ago. Dozens of local, state and federal agencies are assisting with security.
