The two casualties were discharged at the scene.
The PSNI, Northern Ireland Fire and Rescue Service and Northern Ireland Ambulance Service later attended the leisure complex, which is on the outskirts of east Belfast.

The Belfast Telegraph understood the suspicious object was a powder that was being examined by firefighters.
In a statement, a spokesperson for the PSNI said: “At around 2.30pm this afternoon, Police received a report at around that a package had been opened containing an unknown substance.
“Police carried out a public safety operation in the area and the leisure complex was evacuated.
“Colleagues from the NIFRS attended and examined the substance, which was determined not to be a risk.
“Police seized the package and contents for further examination. We would like to thank the public for their cooperation and all cordons have now been lifted.”
