An Evansville man has been arrested after homemade bombs were found inside his home and he threatened to kill an Evansville police officer.
Officers have arrested 48-year-old Franz Corvette Costello on multiple charges.
Police received a tip on Tuesday that Costello was telling people he was going to kill one of the unit's members. Officers also received cell phone pictures that proved he was building homemade bombs.
Police say Costello had been investigated by the Meth Suppression Unit three times in the last year. He served five months in jail after being convicted of possession of precursors stemming from a March 2013 arrest and he was also investigated twice in February of 2014.
The EPD SWAT team took Costello into custody on Wednesday around 1:30 p.m. at his house in the 900 block of North Governor.
EPD bomb squad found three homemade bombs inside the home. Officers say two were in a bag next to Costello's bed and one was under his pillow. Police say the devices were converted mortar type fireworks that had been modified into homemade "fragmentation grenades".
Authorities say the devices had fuses attached to them and were ready to be detonated. Police say the devices were capable of killing someone and causing property damage. The bomb squad was able to disassemble all three of them at the scene.
Officers say meth and drug paraphernalia were also found in the house.
Costello has been charged with possession of a destructive device with intent, possession of meth, possession of syringe and possession of drug paraphernalia.
Police say two other people were removed from the house, but they were not charged with a crime.
