Parcel bomb plot poses difficulties for investigators

Even if gardaí can identify where stamps bought a year ago were purchased, the CCTV is ‘long gone’

The Garda investigation into the parcel bombs posted to London will be a “difficult” one, security sources have warned.

Hopes that the stamps on the parcels could help in the process of identifying the possible sender or senders may be short-lived given that the apparent stamps — special St Valentine’s stamps from 2018 — were purchased more than a year ago.
