JOHNSON CITY, Tenn. -

The grassy area between several student dorms is where a student tells campus police he and a female friend, who is not a student, were robbed at gunpoint.

According to the incident report it happened around midnight Tuesday, but wasn't reported until 12:30 a.m. An ETSU spokesperson does not know the reason for the delayed report.

Police are still looking into the incident while investigating another armed robbery that happened on campus March 26. "We do not have any information right now to suggest the two incidents are related, so the investigation on both is ongoing," says ETSU spokesperson Joe Smith.

But for some students two on-campus crimes, both involving guns, has them on alert. "The first one was a little bit scary but now I'm a little bit concerned. It's making me get more concerned to walk around campus at night than it was before," says ETSU student Emma Flaming.

Both robberies happened at nighttime, and that has some changing their nighttime habits. "I don't go out as much anymore in the past few weeks," says ETSU student Tanner Stewart.

The most recent incident happened between Davis and Centennial Halls, in close proximity to campus police and near one of the many emergency response phones on campus. "It's kind of scary, it makes you wonder. I think about it a lot, but honestly you've got to watch out for yourself," adds Stewart.

ETSU issued a campus-wide alert after the robbery and says it will increase police presence on campus for the rest of the semester.

There is a shuttle service for students who don't want to walk across campus at night. Students can also call campus police for an escort.
