UPDATE 6:30 p.m. (WZZM)- A fire overnight wiped our three businesses and several apartments.

The fire began late Monday night at The Other End Sports Bar on North Michigan Ave. at 4th Street. Flames spread quickly engulfing The Pizza Factory and Suds Laundromat.

Investigators say the buildings were so old that there we no firewalls to slow the fire.

Each business had a second floor apartment. Everyone inside made it out safely.

UPDATE AT 1:00PM - (WZZM) - It is too early to tell, but investigators think they know where the fire that destroyed four Shelby businesses started.

Investigators think the overnight fire began in The Other End Sportsbar and spread to the other businesses.  Schultz Photography Studio, The Pizza Factory, and Suds Laundromat were also destroyed.

Two people who lived in an apartment above the businesses were able to get out safely.

Crews expect to be onsite all day Tuesday and Wednesday clearing the scene. 

UPDATE AT 7:00 A.M. (WZZM) -- Fire departments from Oceana and Muskegon counties are still on the scene of a fire in the 200 block of North Michigan Avenue in Shelby.  The fire is out, but crews are watching for hot spots.

According to witnesses, the fire has damaged a restaurant known as The Pizza Factory, The Other End Sports Bar and Suds Laundromat.  At last report, they said it was threatning at least one other business.

Dan Zuinga owns the laundromat and was visably shaken.

"I was shocked and a little nervous for my renters and renters above the building next door," he said.  "I'm glad everyone got out safe."

Shelby residents say the flames from the fire were visible above the roof lines on surrounding streets.

Derek Prowant was out riding his bike and arrived shortly after the fire started.

"I heard like almost thunder and I thought we were getting some rain.  I looked and like an orange mushroom cloud came up to my house which is directly behind us.  I told my wife to get out.  Downtown is on fire," he said.

Within minutes of the fire starting, dozens of people from the small community came out to watch as much of their downtown was destroyed.

Zuinga says it is possible he may rebuild but it is too soon to say.
