Capt. Marc Limansky, University or Maryland Police spokesman, said Howard was issued a citation about 2:25 a.m. Saturday outside the Shanghai Cafe in College Park, the university newspaper the Diamondback reported.
Police had responded to patrons who reported a fight outside the cafe but Limansky said he didn't know whether Howard was involved in the fight.
"We had the aggressor [in the fight] sit down outside to calm down, and at that point Mr. Howard began taunting the individual, trying to get him riled up again," Limansky said. "Officers told [Howard] to stop what he was doing, but he continued to do it, at which point we placed him into custody."
If convicted, Howard faces a maximum penalty of two months in jail and a $500 fine.
Howard said in a phone interview Sunday he did not provoke anyone or try to start a fight.
"They thought that I was instigating," said Howard, a Los Angeles native. "But people around me said I wasn't. I was speaking to the cops, and that was it."
Howard, a sophomore, averaged 6.5 points and 3.7 assists in 14 games this season.
He had missed the first two months of the season because of a broken foot and missed the final month after tearing his ACL in a February practice.
