CAMDEN, Del., (CBS) — The Delaware State Fire Marshal says two men have been arrested in connection with the discharging of two homemade explosive devices inside a Walmart Store in Camden.

On September 21, state fire investigators were called around 6:30 p.m. to the store at 263 Walmart Drive for an investigation of two suspicious devices exploded inside two separate restrooms.

Fire officials say no one was injured and minimal property damage was reported inside the restrooms.

Investigators were able to follow up on leads which they say led to the eventual arrests of Malcolm A. Casson, 21, and Bradford Joshua Husfelt, 20, both of Dover, Delaware.

Casson and Husfelt were each charged with two counts of Manufacturing and Use of an Explosive Device , two counts of Conspiracy 2nd degree, and two counts of Reckless Exploding.

Casson was committed to the James T. Vaughn Correctional Center on October 18 in lieu of a $6000 secured bond.

Husfelt was released on a $12,000 unsecured bond on October 22.
