Tony Montana says the incident happened in LA back in 2003.
"I went up to order a drink and Kevin came up to me and put his arm around me. He was telling me to come with him, to leave the bar. He put his hand on my crotch," he tells online website Radar.
“I put my hand down and turned his thumb back to get his hand off it. I paid for my drink and got away from him.”
But he says that Spacey then followed him into the toilets. “One of his friends was in line and I said, ‘It’s time to take your boy home.’ They all ended up leaving," he concludes.
