An FBI spokeswoman said the agency suspected a link to previous bombings in the state
US authorities are investigating whether a parcel bomb that exploded at a FedEx depot in Texas on Tuesday is connected to a suspected serial bomber.
The incident occurred at 00:30 (05:30 GMT) in Schertz, 65 miles (104km) south of Austin, where four bombs have killed two people in recent weeks.
One staff member at the depot sustained light injuries, police said.
FBI spokeswoman Michelle Lee told CNN the agency believed the blast could be connected to the four previous attacks.
Local media, citing law enforcement sources, reported that the package that detonated in Schertz was addressed to Austin, and had been packed with metal to create shrapnel.
Three of the four previous devices were hidden in parcels left at residential addresses in Austin. Police said another was probably activated by a tripwire, tripped by two men walking along a street in south-west Austin.
The first device exploded on 2 March, killing Anthony Stephan House, 29, at his home.
Two more bombs exploded 10 days later. Draylen William Mason, 17, was killed and his mother was critically injured when he brought a package inside his home from the doorstep.
Hours later, a 75-year-old Hispanic woman, who has not been named, was injured by another package.
