Michael Lohan, Lindsay Lohan’s father, brought the Los Angeles County Sheriff’s Department to the actress’ home in order to “check on” Ali Lohan, Lindsay’s 16-year-old sister who was staying at her residence, as first reported on TMZ. According to People, cops inspected the house and interviewed Ali before leaving the property. Michael Lohan told, “I went to the police department concerned about Ali’s welfare…I wanted to check on Ali. I wanted to make sure she’s okay. She’s 16 and she doesn’t belong there. She’s a minor.”

After the visit, Lindsay wrote a string of Tweets on her Twitter page, “i have no choice but to make this public, due to my sister’s safety, as well as my own, ‘my ex-dad’ just WALKED INTO MY APT like the devil’s…advocate with officers.”; “He has NEVER paid child support, and is marrying a tabloid writer and can barely spell his own name due to his ‘brain’ that has been ruined”; “due to HIS drug use.”; “when will it ever end… it’s been going on my whole life with him-hasn’t he caused enough pain ?”; “thank g-d for my mommy… w/out her, i wouldn’t even know myself..”
