Texas on edge as police hunt for ‘serial bomber’

Police in Texas are looking for what they suspect is a serial bomber, after an explosion at a FedEx depot. They have identified several people of interest, but no clear suspects have emerged.

A package bomb filled with nails and shrapnel exploded at the distribution centre early on Tuesday.

It is the fifth bombing in the state this month, which police believe are all linked.
