UPDATE 11/30/12 @ 8:50 p.m.
ATHENS, Ohio (AP) -- Campus police and the state fire marshal's office are investigating an overnight fire on the roof of an Ohio University building as arson.

A spokeswoman at the university in Athens in southeast Ohio confirmed that arson was suspected in the fire early Friday on the roof of the school's Research and Technology Center. No one was injured.

She says campus police spotted the fire and Athens firefighters extinguished it.

The fire caused some damage to the building, but no damage estimate was available yet.

OUPD Capt. Brian Kapple said fire investigators with the Division of the State Fire Marshal were called in Friday morning to "process the crime scene."

Media outlets report that Kapple says the fire was in a small wooden structure he believes was once used to house a telescope.

Police said they had no immediate suspects.

The fire was reported just before 12:30 Friday morning at the Research and Technology Center building.

Captain George Cling with the Athens Fire Department says it took about an hour to contain the fire.

No one was injured and the damages were limited to a wooden telescope on the roof.

The building is open for classes on Friday.
