A bus driver was killed when a meteor landed on a college campus in Vellore, India, Saturday, Indian officials confirmed Monday. The explosion also injured three others and shattered windows in several buses.

It was initially thought to be a bomb blast that rocked Bharathidasan Engineering College and gouged a small crater in the ground, but investigators have found fragments of the celestial object leading the conclusion it was a meteorite that killed the 40-year-old man.

Witnesses said the man was drinking water from a tank in the garden when explosion happened. He fell to the ground bleeding and died on the way to a hospital.

"A mishap occurred yesterday when a meteorite fell in the campus of a private engineering college in Vellore district's K Pantharappalli village," Chief Minister J. Jayalalithaa said in a written statement.

Fragments of the meteorite were recovered from his body.
