Cops have arrested two people today after a suspicious package was left in Princes Street Gardens, Edinburgh, in 2018.
A 35-year-old man and a a 32-year-old woman have been arrested in connection with the incident on Thursday, January 11, 2018.
Officers responding to the incident initially thought it was an "elaborate hoax" but soon discovered it was an explosive device with the potential to cause harm.
Investigators tested the suspicious package at the time and said it had proven to be dangerous.
A police statement released following the discovery in 2018 said: "Initial assessment of the package suggested it was an elaborate hoax, however further forensic examination has now confirmed the contents had the potential to cause injury to persons and damage to property within close proximity of it."
Police scoured around 800 hours of CCTV footage for clues following the incident and a number of people who were in the gardens were interviewed.
Now, three years later, a man and a woman have been arrested in connection with the incident.
Detective Chief Superintendent Stuart Houston, Police Scotland's Head of Organised Crime and Counter Terrorism said: “Since the discovery of the item, officers from Police Scotland’s Counter Terrorism Unit have carried out extensive enquiries, including with European partners and law enforcement agencies.
"They have been absolutely committed to this protracted and challenging inquiry to identify those believed to be responsible. This has resulted in the arrest of two people today."
Police activity on Granton Road and on King George IV Bridge today was said to be pre-planned and intelligence-led as officers assured the public there was no wider risk to the community.
Chief Superintendent Sean Scott, Police Scotland's Divisional Commander for Edinburgh, added: "Enquiries by Police Scotland are ongoing and I want to re-assure the public that the activity in Granton Road and on King George IV Bridge was pre-planned and intelligence-led.
"You will see an increased police presence, however, there is no wider risk to the community."
