Brighton's Sussex Square was cordoned off this afternoon after the discovery of an unexploded Second World War bomb.

Initial reports suggested the bomb was found in the basement of the EF International Language school. The Argus understands builders are currently rennovating the property.

UPDATE: The square has been re-opened. Police on the scene say the bomb was an old mortar that posed no danger. It was in fact found on the third floor.

A spokeswoman from Sussex Police said: "Police were called after workmen found an eight-inch long mortar bomb while doing building work on the third floor of the E F International School of English in Sussex Square, Brighton, at 11.45am on Tuesday.

"The building was evacuated and the road closed between Sussex Square and Eastern Road. The bomb disposal unit arrived and collected the mortar which was empty."
