MANCHESTER, Conn. (AP) — The campus of Manchester Community College was locked down for several hours Wednesday after a student reported seeing a man with what she believed to be a gun in his waistband, and one of the officers involved in the response was injured in an accidental shooting.

Police declared the campus secure six hours after the initial report was made but said they were still looking for the person the student described.

The wounded officer’s foot was struck when a weapon accidentally discharged, police said. He was taken by police cruiser to Hartford Hospital. His name and condition weren’t released.

When the student reported seeing a man with a gun shortly before 2 p.m., the college sent an alert to students by text message and called Manchester police. Classes were canceled for the day and people were told to stay out of the halls as police conducted their search. Investigators gave the all-clear in a statement at 8 p.m.

Students were urged to stay away from campus as police armed with rifles searched and cleared the buildings one classroom at a time. The police statement said the search was ‘‘a methodical task’’ involving many classrooms, some of which had several hundred students inside.

A couple hours after the alert, college president Gena Glickman had said authorities were confident the situation was under control.
