An employee in the mayor’s office called police after opening a letter containing an unknown white powder.
A section of the 3rd floor offices were evacuated as a precaution.
Preliminary reports indicate the white powder is benign, according to LAPD Commander Blake Chow.
Turns out, the substance was harmless chalk.
The envelope also included a “threatening letter” addressed to Villaraigosa, Chow told the L.A. Times.
He said it appears the envelope may have been sent from a correctional facility out of state.
