Michael told RadarOnline: "I'm so worried about the people around my daughter; she continues to surround herself with people that are going to hurt her.
"It's sad and very scary what is happening to Lindsay. I just what her to get it right."
"Ali is literally the only person I know that can help her. Right now all she needs is her family. Her mother Dina, siblings Michael, Cody, Ali and I are the only ones that can help her stay sober. She needs to come home literally and metaphorically. Dina and I are in a much better place to support her in her sobriety."
While Michael would love if his 25-year-old daughter attended university with her younger sister, he believes she needs to go back to rehab first.
He added: "Maybe Lindsay should go to college with Ali.
"What will it take for her to listen? Jail is not the right place for her, but she needs to go to a rehab that understands her problems. She has been to some of the worst rehabs in the country. Just because they have a name doesn't mean can help her."
