Bloomington, Ind. ? Basketball fans upset by Indiana’s loss in the NCAA championship torched couches, toppled street signs and threw beer bottles at officers, while Maryland fans set bonfires and shot off fireworks in celebration.

Bloomington officers broke up the crowd with tear gas, sending hundreds of students and fans from an intersection near the edge of the Indiana University campus at about 1:30 a.m. Tuesday.

About 30 people were arrested on charges including public intoxication, criminal mischief and disorderly conduct, police said. Four others were charged with battery on a police officer.

“When students started getting pelted with bottles that’s when we decided to move and disperse the crowd,” Bloomington Police Capt. Mike Deikhoff said. “If the crowd hadn’t started throwing beer bottles and setting fires we wouldn’t have had to act.”

The violence came after some students and fans turned bitter following Indiana’s 64-52 loss to Maryland late Monday.

In Maryland, police on horseback pushed thousands of revelers off the streets early Tuesday, trying to rein in a victory celebration by fans ecstatic over the school’s first national basketball championship. A total of 15 people were arrested by university and Prince George County police, with charges ranging from aggravated assault to disorderly conduct, an official said.

“This is terrible. We’ve finally started to lose the reputation as the Len Bias death school, and now we’re known as the riot school,” said student Josh Fingold, 21, referring to the 1986 cocaine overdose death of the Maryland basketball star.

Despite the victory and an increased police presence, the Maryland crowd turned riotous, breaking the window of bicycle shop, throwing bottles and other objects at police and lighting bonfires.

Several officers suffered minor injuries when they were struck by bottles and other objects, said state police Lt. Bud Frank.

The damage in Maryland did not appear to be as bad as after last year’s Final Four loss to Duke when one bonfire caused an estimated $500,000 in damage and disrupted cable service when it burned through a fiber optic line.

Maj. Jeff Cox, head of the Prince George’s County police department’s patrol unit, said most of the revelers did not cause trouble, blaming a few rogues.

“I wish I knew why we keep having this problem. I’m hoping tonight we found the formula for taking care of it,” Cox said.
