A man has pleaded guilty in an election-night rampage against black people last year in the wake of Barack Obama's victory as the first African-American U.S. president.

Prosecutors say 18-year-old Ralph Nicoletti faces 12 years in prison. He pleaded guilty Monday to assaulting residents of New York City's Staten Island borough on Nov. 4 in retaliation for Obama's election.

Three friends — two white men and a Hispanic man — previously pleaded guilty.

They had been accused of beating a Liberian immigrant teen, pushing a black man to the ground and driving their car over a white man they thought was black.

The last victim was in a coma for several days but survived.
