LOS ANGELES -- The schools in Los Angeles are safe and will reopen Wednesday, Los Angeles Unified School District School Board President Steve Zimmer told reporters.
"We can now announce, and conclude, and tell you, and tell the community that we believe that our schools are safe, and we can reopen schools in the Los Angeles Unified School District tomorrow morning," he said.
The FBI has determined that a threat against schools in the city was not credible, Mayor Eric Garcetti said.
"Whether it's criminal mischief, whether it's somebody testing vulnerabilities of multiple cities, we still do not know enough to say definitively," he said. "What we do know is that it will be safe for our children to return to school tomorrow."
At the press conference, officials defended the decision to close down schools for the day.
"I think that anything can be viewed with a mirror into the past, but when decisions were made, the information that we have now was not available," Los Angeles Police Chief Charlie Beck told reporters Tuesday evening.
Steven Zipperman, police chief for the school district's police department, said more than 2,700 officers were involved in walk-throughs at more than 1,500 school sites Tuesday.
"That's a lot of resources, resources wisely used," he said. "All of us can go to bed tonight with a lot more comfort knowing that all of our schools have been checked."
