Milwaukee ? Three white former police officers were sentenced to long prison terms Thursday for the off-duty beating of a biracial man, an attack that outraged the city and sent protesters into the streets.

A judge sentenced Jon Bartlett to 17 years and four months. Daniel Masarik was sentenced to 15 years and eight months, and Andrew Spengler received the same sentence. Each of the three also was sentenced to three years supervision and ordered to pay $16,365 in restitution.

Bartlett, 36, Masarik, 27, and Spengler, 28, were convicted with another former officer for taking part in the beating of Frank Jude Jr. outside a housewarming party in October 2004.

Jude, 29, said he had been at a party on Oct. 24, 2004, when a group of white men who identified themselves as off-duty officers kicked and punched him, put a knife to his throat and jammed a pen in his ears as he begged for mercy. Jude said he heard Spengler call him a racial slur.
