The disruption to campus life at the Newark, New Jersey campus of Rutgers University began Tuesday night, but continued into Wednesday with several streets blocked off and swarming with police, fire, bomb squad units and even the FBI.

"They used shuttle buses to block the streets. You had a whole bunch of cops over here," said Rutgers student, Danny Bishara.

No classes were cancelled, but three dorms were evacuated. According to Rutgers University, the alarming scene stemmed from a tip coming from the University of South Dakota.

There, according to a spokesperson, the search of one student's room led to the discovery of "something that could be considered explosive in nature." While South Dakota officials said they believe the incident to be isolated, Rutgers was informed of a connection to one of their own students.

A 19 year old living at the University Square dorms was arrested on multiple charges after the bomb squad found "potentially dangerous materials," according to Rutgers officials. That student's friends, however, say all of this is a misunderstanding and their friend has already returned to classes.

"He wouldn't do something that would risk himself getting in trouble, " said Rasheed Abdulla.

The FBI says they've found no danger on the Rutgers campus, but their investigation into the South Dakota incident remains ongoing.
