Three vehicle fires sparked an investigation on the University of Connecticut Storrs campus.
Police said the fires were intentionally set just before 5:30 a.m. on Sunday.
State police and fire personnel responded to the Carriage House apartment complex to investigate.
They found that a residential apartment may also have been targeted.
"I think it was almost like a revenge plot - two kids didn't get into a party," said student Patrick McGarity.
One student was away for the weekend and she came back to campus to find her SUV torched.
Another student's car appeared to be the first car that was set on fire, and then the flames spread to the cars on either side.
Some students said someone may have even poured gasoline on a front door, as there are charred marks at the bottom.
"I've been to Carriage House before but I've never seen this before - its pretty serious stuff," said student Conner Tluck.
No injuries were reported.
Officials said the fires were quickly controlled and extinguished.
Anyone with information is asked to call state police detectives at 860-896-3200.
