Ammonia leak prompts evacuation of Central Park Athletics

More than 25 people were evacuated and a hockey game interrupted by a small ammonia leak at Central Park Athletics Sunday.

Fifteen firefighters responded about 11:30 a.m. Investigators believe the leak was caused by a broken valve.

There were no injuries. The building re-opened about 5 p.m.

Ammonia is a chemical used in the refrigeration systems of many ice rinks.

The rink was built around 1949. The refrigeration system was closed for repairs for two weeks in September.
