LOUISVILLE, Ky. (WDRB) -- Louisville Metro Police arrested a 53-year-old man in connection with an investigation involving hazardous materials at a home in the Highview neighborhood Thursday evening.

Aaron Ellis, a spokesperson for LMPD, said a search warrant was served at a residence on Applegate Lane due to an investigation involving hazardous materials.

Police arrested Marc Hibel, 53, in connection to the investigation. He's been initially charged with wanton endangerment.

According to an arrest citation, LMPD responded to the home after it received information that Hibel "may be in possession of homemade explosives."

Once on scene, police said Hibel invited authorities into the home and showed them what he called homemade explosives, using TNT. Police said he also made statements that he had made explosives and homemade blasting caps in the past, which he detonated in his backyard. 

The arrest report goes on to say that while Hibel was being mirandized, he admitted to possessing TNP, or Picric acid. According to the National Library of Medicine, TNP is an explosive. 

Police said Hibel "is a chemist by trade and admitted to possessing laboratory-grade equipment and chemicals." 

"Detonating explosives in a residential area creates a substantial danger of death or serious physical injury," police said in the arrest report. 

Authorities conducted a controlled detonation of "a device" behind the property. Police said it was a controlled event and there was no danger to the public.

The FBI said it's assisting LMPD in the investigation. 

Hibel is expected to be arraigned in court Friday morning.
