CNN) -- A bullet that flew through a building at the University of Texas at El Paso may have crossed the U.S.-Mexico border during a shootout between drug traffickers and Mexican federal police, authorities said.

University President Diana Natalicio said Sunday a bullet struck Bell Hall sometime Saturday evening. No injuries were reported at the building.

That same evening, a "major gun battle" between drug traffickers and Mexican authorities broke out in Ciudad Juarez, Mexico, just 30 yards from the U.S. border at El Paso, Texas, a U.S. Border Patrol spokesman said.

Three police officers were injured and one armed suspect was killed, federal police spokesman Ramon Salinas said.

During the fire exchange, U.S. authorities blocked off a section of Paisano Street, which runs parallel to the Rio Grande.

Natalicio said campus police determined a bullet went through the glass panel of the building's door and lodged in an office door frame.

"This appears to be the only stray bullet to have struck the campus," Natalicio said. "There is no evidence to suggest that UTEP was specifically targeted."

Natalicio said the university will consult with law enforcement and government officials about possible further security precautions.

The shootout took place less than two months after shots fired from a gun battle originating in Juarez crossed into El Paso and hit City Hall, damaging the building.
