A package has exploded at a FedEx distribution center in Schertz.

The facility is just northeast of San Antonio and officials confirmed the incident was connected to the four recent explosions in Austin.

“We are trying to understand what happened, shift through the evidence, and let the evidence take us to where we need to go,” said James Smith, FBI assistant special agent in charge

The package bomb exploded around 12:30 a.m. Police say the medium sized box was on a conveyor belt when it exploded. Officials say the package contained metal shrapnel and nails and was heading to Austin.

"A Package had been traveling along the automated conveyor when it had exploded. One employee standing near the explosion made a complaint of ringing in the ears, she was treated and released, we were very fortunate that there were no injuries," according to Schertz Police Chief Michael Hansen. 

About 75 people were working in the facility at the time of the explosion. One female employee sustained a concussion when the package detonated. 

Federal agents spent about 5 hours inside the Schertz FedEx site. They left the scene shortly before 4:00 Tuesday afternoon without commenting about what they collected.

While the FBI has not officially confirmed it, officials in Sunset Valley say the package originated from a FedEx in Sunset Valley.
