MEXICO CITY - Mexican actor Roberto Cavazos accused Kevin Spacey on Tuesday of sexual harassment, echoing claims made by actor Anthony Rapp and predicting a "whole lot more" accusations against the two-time Oscar winner will emerge.

Cavazos, who acted in several plays at London's Old Vic theater when Spacey was artistic director there, said the Hollywood star routinely preyed on young male actors.

"It seems the only requirement was to be a male under the age of 30 for Mr Spacey to feel free to touch us," he wrote in a Facebook post.

He said Rapp - the American actor who accuses Spacey of making a "sexual advance" when he was 14 and Spacey was 26 - was far from alone.

"Those of us who crossed paths with (Spacey) in London when he was director of the Old Vic know a whole lot more people will find the courage to tell their stories in the coming days and weeks," he said.

"It wouldn't surprise me if there were similar numbers to Weinstein's," he added, referring to the dozens of women who have accused Hollywood mogul Harvey Weinstein of sexual assault and harassment, unleashing a torrent of similar accusations against a growing list of rich and powerful men.

The Old Vic on Tuesday said it was "deeply dismayed" by the allegations against Spacey and encouraged anyone with stories of abuse to contact the theater via a confidential email address. - AFP
