Three people are in custody after a shot was fired in a St. John's University dorm.

In a photo tweeted by a student (seen above), you can see a heavy police presence outside Hollis Hall at the school's Queens campus.

According to school safety officials, three males entered the dorm around 1:30 p.m. Wednesday and got into a verbal dispute.

Police say a single shot was fired as the suspects tried to take money.

The NYPD says the bullet went into a wall and that two of the suspects had guns.

No one was hurt.

NY1 spoke to a student who lives directly below the dorm room where the incident happened.

"It just sounded like a lot of thuds and bangs, so we just, we didn't think anything of it. I'm like, 'Oh, maybe they're fighting,'" the student said. "So then we hear like a bang and we're like, 'Well, what's that? Sounds like a gunshot.' 'Well, I thought a gunshot would of been louder than that.' And we're just surprised."

St. John's released a statement saying there is no threat to the campus and that they are cooperating with the NYPD's investigation.

Charges against the three suspects are pending.
