Milwaukee, Wisconsin - Twenty people were injured in two shootings in downtown Milwaukee near an entertainment district where thousands of people were watching the Bucks play the Celtics in the NBA's Eastern Conference semifinals, authorities said.
None of the injuries from either shooting were believed to be life-threatening.
The first shooting Friday night, involving three victims, occurred adjacent to the Deer District - an entertainment district with numerous bars and restaurants where large crowds often assemble for major sporting events.
The Milwaukee Fire Department said authorities took two people to a hospital, a 30-year-old man and a 16-year-old girl, and a third person drove to a hospital. Police said a 29-year-old man was in custody.
Seventeen more people were injured in a second shooting about two hours later, which happened a few blocks away. Ten people were taken into custody and nine guns were recovered, local station WTMJ-TV reported.
There was no immediate indication whether the two shootings were related or involved fans who were watching the game.
Witnesses told WTMJ-TV that they saw a fight outside a bar following the basketball game.
Bill Reinemann, a parking attendant at lot adjacent to Deer District, said he heard gunshots but didn't see anyone get shot or see the shooter during the earlier shooting.
"It sounded like six to eight gunshots," he said "It was close."
After the shots were fired, scores of fans began running toward the Deer District, he said.
Reinemann, who has worked the lot for 18 years, remained at his post even as fearful Bucks fans ran past him.
"I sat in my chair here the whole while," he said.
"The incident took place outside of the Deer District area. We direct all questions to the Milwaukee Police Department," Bucks spokesman Barry Baum said.
Boston defeated Milwaukee in the game to force a Game 7 in the series.
