Police say they've arrested 27 people, including some University of Maryland students, after hundreds of basketball fans turned confrontational near the College Park campus.

Police spokesman Cpl. Larry Johnson says about 1,500 people poured onto U.S. Route 1 in Prince George's County after Maryland beat No. 4 Duke 79-72 Wednesday night.

TV footage showed officers on horseback dispersing the crowd and police in riot gear patting down young men. Johnson says some in the crowd threw snowballs and ice at police and some officers suffered minor injuries.

Johnson says charges ranging from civil disturbance to destruction of property are pending against those arrested. Campus police say smaller groups there set fire to a tree and trash cans.
