Officers from the South East Counter Terrorism Unit (SECTU) are currently investigating a series of suspect packages sent to Army Careers offices across the region.
So far seven suspect packages have been received at the following locations:
Armed Forces Careers Office, St Marys Butts, Reading, and the Army and RAF Careers office at Dock Road, Chatham, Kent, on Tuesday (11/2).
The Army Careers Office, Hospital Hill, Aldershot, Hampshire, yesterday (12/2).
Army Careers offices in St Giles, Oxford, Queensmere Shopping Centre, Slough, Queens Road, Brighton, and St Peter's Street, Canterbury, today (13/2).

The contents of the packages are suspicious in nature and will now be sent off for forensic examination. Even if the contents are determined to be a viable device they pose a very low level threat and are unlikely to cause significant harm or damage. When a suspect package is reported we have a routine response which means we may need to evacuate the area if necessary until we can be sure it poses no threat to the public. Whilst this can cause concern and disruption for local communities, it is a necessary precaution until we know what we are dealing with.”
