Bomb disposal experts have left Crawley after examining a suspicious envelope sent to the office of MP Henry Smith.
A spokesman for Sussex Police said: “A military Ordnance Disposal Team have examined the envelope and have established that it is of innocent origin.
“Police are now in process of leaving the scene and the incident is closed.
“We thank the occupants of the buildings that were evacuated, and anyone else in the vicinity who was inconvenienced, for their co-operation and understanding while the envelope was checked out.”
The area, in Stephenson Way, Three Bridges, was evacuated at around 11.45am today (Wednesday February 19) after an odd-shaped package was delivered to Mr Smith’s office.
