CHARLOTTE, N.C. -- A 20-year-old student was removed from UNC Charlotte after allegedly telling a doctor he wanted to shoot up the school.

The mental health professional took that information to police who obtained a search warrant for the man's home. No guns or explosives were found.

"I think it's definitely important to pay attention to the warning signs," said student Hannah Mynes.

Court documents showed the student said he loves "watching humans getting killed" and could not wait to buy a gun and shoot the university up.

The documents also said the man had been watching YouTube videos of Columbine and other school shootings, concluding most school shooters are not successful, because they don't plan the attack.

"I'm just trying to worry about my papers and my readings and not whether or not I should be fearing for my life," student Sarahan Moser said.

Police said the 20-year-old was voluntarily committed to a hospital for a mental health evaluation,

and authorities told NBC Charlotte they'll be notified if he's released.

"I would hope people would be following him following his actions because these are all the warning signs we see," Moser said.

The UNC Charlotte police chief sent us a statement saying, "Due to federal privacy law, we cannot comment on any specific steps that have been taken."

"I hope UNC Charlotte steps up to the plate and does something to protect us," said Moser.

The police chief said the man has a clean record, and so far, no charges have been filed, but it is an active investigation.

Documents showed the student has been removed from UNC Charlotte but planned to stay at a nearby apartment complex.
