CORPUS CHRISTI (Kiii News) — The Corpus Christi Fire Department responded just before 11 a.m. Thursday to a structure fire at an old empty storefront in the 2700 block of South Port Avenue.

As firefighters worked to get the blaze under control, what appeared to be a hand grenade was found inside the structure and the Corpus Christi Police Department Bomb Squad had to be called to the scene.

Firefighters said the structure appeared to be an abandoned storefront with a warehouse in the back. The fire was contained to the front portion of the structure.

Along with what appeared to be a hand grenade, firefighters also said they found drug paraphernalia there as well.

Firefighters had to back off from the scene as the Bomb Squad got to work investigating to see if the hand grenade was live or not. Thankfully, it was not.

"There's no live hazards inside. Nobody was found inside. No injuries to firefighters as well," Assistant Fire Chief Kenneth Erben said.

Police said it turned out to be a training grenade or just a shell and did not contain an explosive.

Firefighters put out the remaining hot spots, keeping a portion of South Port Avenue closed while doing so, and began leaving the scene by around 3:30 p.m. The cause of the fire is still under investigation.
