MILFORD, Conn. (AP) A Connecticut man has pleaded guilty to weapons charges stemming from a gun scare last year at the University of New Haven.

Authorities say William Dong, a former UNH student, pleaded guilty Friday to illegal importation of a semi-automatic Bushmaster that he had in his car and illegal possession of pistols that he brought onto campus.

State's Attorney Kevin Lawlor in Milford said the plea agreement calls for a mandatory minimum of two years in prison, followed by five years of probation. Sentencing is set for Dec. 19.

The campus was locked down for more than four hours Dec. 3, 2013, as police arrested Dong and searched the school grounds.

Police say they found 2,700 rounds of ammunition and newspaper clippings about the Colorado theater shooting at Dong's home.
