You're never going to believe this, but this involved Lakers fans.
Via the Greenfield Patch, following the March 28 game between the Lakers and Bucks, two roommates squared off because, well, one wouldn't boo his hometown Bucks.
According to the Greenfield Police Department report, a 20-year-old woman called police to report her 19- and 18-year-old roommates were in a fistfight outside their apartment in the 3300 block of South 110th Street.
When a police officer arrived, he saw two shirtless teenagers facing each other with fists raised and ready to fight. The officer ordered them to cease, but they simultaneously lunged at each other and exchanged blows. The fight lasted for only a few seconds before the men listened to the officer's demands to end the fighting.
The woman told police the three of them and a fourth roommate, a 30-year-old man, went to the BMO Harris Bradley Center earlier that evening to watch the Milwaukee Bucks take on the Los Angeles Lakers. The 19-year-old man would not boo the Bucks, leading the 30-year-old and 18-year-old, both Lakers fans, to verbally harass him and call him names, the woman told police.
Once back at the apartment, the 30-year-old urinated in a garbage can in the 19-year-old's bedroom.
The 18-year-old was arrested on disorderly conduct -- domestic violence, for threatening the woman. The 19-year-old was also arrested for disorderly conduct -- domestic violence for fighting.
And you're never going to believe this, but the article says that alcohol is believed to have contributed to the altercation.
Oh, and of note: The Bucks won that night over the Lakers, 113-103.
