Prosecutors in western Mexico say they have opened a criminal investigation into complaints of sexual harassment aired by the country's exploding "#MeToo" movement.

The prosecutors' office in Michoacan state said Wednesday that some of the complaints published on social media constituted possible crimes that occurred in the state and therefore fall under its jurisdiction.

Mexico had a tepid response to the original #MeToo movement that sprang up in 2017. Only a few Mexican actresses said they had been harassed, despite reports that abuse was widespread.

But over the last few days, the United Mexican Journalists group says it has gathered over 120 allegations of sexual harassment across the country's biggest media outlets.

Similar campaigns have sprung up on social media for Mexican writers, academics and activists to share their stories.
