A college information session in the District attended by thousands of students was called off Tuesday after fighting broke out, authorities said.

Near the end of the morning session, “a few students started some pushing and pulling,” said a spokesman for the D.C. State Superintendent of Education, a co-sponsor of the event at the Walter E. Washington convention center.

He said everything calmed down after police arrived, and no injuries were reported. A police spokesman reported no arrests.

The morning event was suspended about 11:45 a.m., and a complaint about noise led to the cancellation by the convention center of a scheduled evening session, said Marc Caposino, a spokesman for the superintendent of education.

He estimated that 7,000 students went to t he convention center for the event.

On its web site, the National Association for College Admission Counseling, described as a co-sponsor, said the Washington fair enables students to get information from representatives of colleges on topics such as college admission requirements and financial aid.

Convention center officiails released this statement Tuesday night:

“Public safety remains our utmost concern and priority for our attendees. Therefore, after disruptive activity and for the safety of all visitors, including those at the college fair and at other events in the building, the Events DC staff determined that the college fair’s evening session had to be cancelled. We are grateful that our operations team and the show organizer worked with the Metropolitan Police Department to control the situation swiftly and no one was hurt.”
