CINCINNATI -- Police say a pair of 20-year-olds set fires in an under-construction luxury apartment building overnight.

Duncan Ray and Ryan Barnes got into the high-rise building between Eighth and Sycamore through a parking garage before setting fires in a bathroom and common area on two different floors, according to police.

Both men appeared in court Wednesday morning, each charged with arson for one fire, though police said they're suspected of setting several others.

The pair started setting fires on Court Street Downtown, according to police. They were targeting things like port-a-potties. Security cameras recorded them setting a fire in an alley outside the library.

Katy Crossen with the Al Neyer Co. said the company is still hoping to keep construction of the luxury apartment building on schedule.

"This does present an unexpected challenge," Crossen said. "We had hoped to deliver it early, and this presents another challenge we're going to work through."

The building was supposed to be finished in November or December.

Ray and Barnes were being held in the Hamilton County Justice Center with bond set at $250,000 each.
