WILLIMANTIC, Conn. (AP) - Willimantic police have arrested several Eastern Connecticut State University students during an annual weekend party known as the "Stumbler."

Police say they responded to 11 separate complaints about house parties on Saturday, the kick-off for the non-sanctioned, off-campus event.

Police say they received about two dozen calls about large groups of people obstructing traffic and other "mischievous behavior."

Police haven't released the identities of the students who were arrested.

Police say they also issued 16 citations for "belligerent behavior" and other drinking-related offenses. Police say full cans of open beer were thrown at city police officers on Chestnut Street. No police officers were injured.

Cpl. Stanley Parizo Jr. says the department is "very disappointed" with the students' behavior.

ECSU is a public, coeducational liberal arts university.
