A Royal Mail delivery office in Chatham was at the centre of a bomb scare today after reports of a suspect package.

Staff at the Best Street office called police at 9am to report the parcel and a 100m cordon was set up around the site.

But after the item was examined by a team from the Royal Logistic Corps bomb disposal unit, Kent Police confirmed it was a false alarm.

It came less than a week after explosives were sent to the Army careers office in Dock Road and another recruitment centre in Canterbury - sparking fears of "Northern Ireland-related terrorism".

Police set up a cordon around the depot, with a patrol car blocking the road. Roads were reopened around two hours later.

Witnesses said officers were talking to Royal Mail staff, who are already on high alert after the previous suspect packages, in the street.

Royal Mail and military staff had been told to be extra vigilant after a spate of suspect packages were sent to Army careers offices.

And screening procedures for mail to recruitment centres was under review.

Kent was at the centre of a major counter-terrorism operation when seven packages - with the devices described as crude but "viable" and having the potential to injure - were sent to Army offices in the south east.

The discovery at Canterbury's Army careers office in St Peter's Street on Thursday came two days after a "basic, but viable explosive device" was found by military recruiters in Chatham.

Dissident Irish Republican terrorists are being blamed on the spate, but no specific group has claimed responsibility.

Prime Minister David Cameron chaired a meeting of the Cobra crisis committee to discuss the government's response to the threats.
