The Raynham IcePlex remains closed after an suspected ammonia leak Wednesday afternoon.

Raynham Fire Chief Bryan LaCivita said firefighters were called to the Broadway ice rink just before 2 p.m. after receiving reports of a fire alarm sounding.

Firefighters discovered that a smoke detector was going off in the mechanical room, according to the fire chief.

LaCivita said firefighters made their way through the ice rink and noticed an ammonia alarm beacon was flashing.

The Massachusetts Hazardous Materials Emergency Response Division rushed to the ice rink to investigate. LaCivita said their initial readings detected elevated ammonia levels in and around the mechanical room.

No one was injured and the cause of the suspected ammonia leak remains under investigation at this time. LaCivita said the ice rink is closed until further notice.
