Third letter bomb sent to company

The three firms provide forensic evidence to the police

Police investigating two letter bombs sent to firms in Oxfordshire have said a third package has been found.

A company in Chelmsley Wood, Birmingham, reported receiving an A5 jiffy bag containing a firework-type explosive on Thursday afternoon.

The name of an animal rights campaigner and convicted fire-bomber, who died in 2001, was written on the envelope.

Police believe the incident is linked to two others in Oxfordshire, in which a woman, aged 40, was injured.

The worker at Cellmark in Blacklands Way, Abingdon, suffered a minor injury to her hand when she opened the package on Thursday morning.

Another letter was sent to a firm in Culham, near Abingdon, but failed to explode.

Acting Deputy Chief Constable Alex Marshall, of Thames Valley Police, said: "Three companies, all of whom provide forensic services to the criminal justice system and police, have been targeted in this series of incidents.

"Although we await full forensic examination, these all appear to have been viable devices and it is fortunate that no one was more seriously hurt."
