Chinese college student to be deported after buying guns

I have the same question as the OP:

How does the BATFE know that he had a AR-15 and ammo?

The first paragraph states that a friend of his and a room mate went to school officials with the info. I would guess that they told the school what the guy was doing, that he had guns and was not acting normal. The school then went to law enforcement.

As far as this goes:

"Campus police received information that Sun had altered his appearance and his behavior was changing, the chief said. They contacted the Bureau of Alcohol, Tobacco, Firearms and Explosives and were told Sun owned an AR-15-style rifle and ammunition."

I doubt that is how it actually happened, this is probably an example of poor journalism or simply an idiot in the campus police dept relaying info about something they know little about.
