The roof of a Phoenix skating rink has partially collapsed.
The Rollero Family Skating Center posted on its Facebook page that the rink will be closed "until further notice" as a result of the damage sustained Tuesday night after the ring had closed.
Phoenix Fire Department Cpt. Larry Subervi says the cause of the collapse is not yet known, although authorities say early speculation points toward the age of the building being a contributing factor.
Subervi says no firefighters or civilians were injured in the collapse.
He said the structure was built with a bowstring-type roof that were popular before the 1960s. he said these types of buildings pose a threat to firefighters because they fail rapidly under fire conditions. He pointed to the 2010 death of two Chicago firefighters when the inside of a bowstring building collapsed.
