NEW HAVEN - New Haven police say they have arrested the person behind a hoax that prompted a massive lockdown at Yale University back in November.

Police say Jeffery Jones, 50, called 911 claiming his roommate was going to shoot people on campus.

Officers arrested him on Tuesday, after comparing his voice to a recording of that call.

"I cannot tell you and emphasize how serious this was," says Assistant Chief Archie Generoso, of the New Haven Police Department. "A number of people were put at risk, including police officers and citizens of the city."

Police say they believe Jones is responsible for a series of other crimes, including vandalism and a similar phone call made to a high school in New Haven.
