Michael Lohan and several others showed up at Lindsay's house Friday afternoon, believing she has fallen off the wagon and they believe that's why she has become a no-show for post-production work on her upcoming movie, "The Canyons."
Michael claimed his 26-year-old daughter is surrounding herself with "a bunch of alcoholics and drug addicts."
Lindsay was at the house when Michael and team arrived, but someone claiming to be her boyfriend shooed them away and the police were called to report a trespassing call, TMZ reported.
The 'Liz and Dick' star's mother Dina said her ex-husband Michael's attempt to stage an intervention was just another ploy to make himself relevant again.
"This sole act by my ex was not an intervention nor was this extreme antic sanctioned by any member of Lindsay's family or her professional team of handlers.
"It's all about her father obsessed with making a name for himself in the news once again. It's sad and I hope he stops masquerading as her father in public and starts acting like one in private," said Dina.
