Heller, president and CEO of Talent Resources, is the man behind Lindsay's appearances in Africa.
Michael's reaction comes after picture of Lindsay partying wild in Africa has emerged, in which she is seen sitting beneath the disc jockey's table in dishevelled condition, reports radaronline.com.
In the letter to Mike, son of Lindsay's attorney Mark Heller, Michael has written: "I am telling you now if you are with Lindsay in Rio or you booked it, and anything happens to my daughter, I am holding you personally responsible.
"Judging from what has happened to in the past, and the way she looks down there from the pictures in the media, it's not a good thing. If you have anything to do with her being there, its on you. Count on it."
