"We have also confirmed that the individual responsible [for Tuesday morning's package bomb] also shipped a second package that has now been secured and turned over to law enforcement," FedEx said in a statement.

"We have provided law enforcement responsible for this investigation extensive evidence related to these packages and the individual that shipped them collected from our advanced technology security systems," FedEx said. "The safety and security measures in place across the FedEx networks are designed to protect the safety of our people, customers and communities, and to assist law enforcement as appropriate."

The blast Tuesday is the fifth in a month in the city.
