Emergency at TGI Fridays?

I was at TGI Fridays just a little while ago and the alarms went off and everyone was kicked out of the building... Soon later, a bunch of police officers and security guards pulled up. Does anyone know what happened? P.S. This was the TGI Fridays in Lake Grove so if you don't know where I'm talking about then you probably don't know what happened... I don't really expect any answers but why not post this and give it a try! At least I got free food too!
