An overzealous Madonna fan has been convicted of resisting arrest after police detained him outside the singer's New York home in 2010.

Former firefighter Robert Linhart reportedly parked his car outside Madonna's apartment block, laid out a huge canvas and spray-painted love notes addressed to the superstar.

He was detained by police, but was accused of resisting arrest on 21 September, 2010.

Linhart denied the allegation, but was found guilty on Friday (09Nov12) after a trial in the Big Apple and he now faces up to a year in jail, according to the New York Post.

He was acquitted of a second charge of resisting arrest stemming from a run in with police several days earlier on 18 September, 2010.
