Two men are under arrest and another is on the loose after a meth lab explosion in Clinton County.

The explosion happened Monday night at the Country Village Mobile Home Park in Clinton County.

"All of a sudden I just feel the trailer shake a little bit and then I heard this really big boom," Courtney Hansen said.

"A bunch of smoke was rolling out the front (of the house)," Jeremy McCarthy said. "I thought it was my house."

James Eimer and Michael Clayton Kelley, both from Grand Ledge, were arrested at the scene, but police are still looking for the third man behind the explosion.

"When our people arrived one of the individuals was getting rid of some of the product by dumping it outside the trailer," Clinton County Sheriff Wayne Kangas said.

Sheriff Kangas says the men were making the meth in one trailer and then took the product to another trailer to cook it. It was inside the second trailer where the explosion occurred.

"Usually in this method it's the reaction between lithium and liquid," Detective Fritz Sandberg said.

"I think it would be like a concussion grenade," Sheriff Kangas said of the explosion.

The explosion rattled neighbors and now has police urging everyone to be on the look-out for meth labs.

"Odor is a big one," Detective Sandberg said. "If you're smelling some strange odor coming from a neighbor's residence it doesn't hurt to make a phone call."

Other neighbors in the area say the explosion was scary, but not too shocking for the area.

"I'm surprised it's my neighbor, but I'm not surprised it happened in this park," McCarthy said.

Police say the third man still on the loose has burns on both of his arms and will need medical treatment.
