A former Olympic sprinter from Trinidad and Tobago was sentenced to 21 years in prison yesterday after pleading guilty to raping a woman in a New York park.

Prosecutors say 31-year-old Alvin Henry was dubbed the Lover's Lane Rapist for secretly recording a woman having sex in the park with her boyfriend. They say he followed the woman and threatened to show the video unless she had sex with him.

Henry was charged with attacking women in parks in Brooklyn and Queens. He admits one of his victims was a woman in Prospect Park in June 2007. He pleaded guilty on Wednesday.

Henry was a member of Trinidad and Tobago's 2000 Olympic 400-meter relay team.
