Lindsay Lohan's father staged an emergency intervention on Friday (19.10.12) which ended in police being called to her Los Angeles home.
Michael Lohan is so worried about his troubled daughter following a number of recent incidents including a huge fight with her mother Dina and allegedly failing to show up for post production work on her movie 'The Canyons' this week that he got together a team of people to try to help her.
Michael reportedly believes the 'Liz & Dick' actress - who has had numerous stints in rehab - has fallen off the wagon but he and those he arrived at her home with were reported for trespassing.
According to gossip website TMZ, a man claiming to be Lindsay's boyfriend asked the group to leave and he said any problems she may have can not be solved by her dad.
Michael recently blasted the party-loving crowd that Lindsay has been spending time with in New York City and blames their "misguided morals" for her recent bust-up with her mother- where she accused Dina of being high on cocaine before retracting her claim - and her public spat with a Congressional aide.
Venting in an email to a newspaper, Michael wrote: "I am very upset with the crowd around Lindsay. My advice to ALL the negative influences in Lindsay and my other children's lives is, this time, you have crossed the line and bitten off a lot more than you can chew!
"My family will not be subject to your misguided morals and ways! There WILL BE changes!! Just watch. (sic)"
However, the actress has said she is "done" with her father after he betrayed her trust by making public a conversation they had about her fight with Dina.
Lindsay, 26, insisted: "I told my dad a really hurtful and untruthful lie about my mom. She was not on cocaine.
"Daughters have fights with their moms. It happens a lot. It's normal."
