In a statement through its twitter account Monday, Iran’s ambassador to the UK, Hamid Baeidinejad, said the ship is now free to leave, pursuant to the completion of the judicial and legal process.
Stena Impero was detained along with its 23 crew members by Iran’s Revolutionary Guards on July 19.
The seizure of the ship attracted media attention in line with an ongoing crisis in the Middle East.
Iranian forces released seven non-essential crew members earlier in September.
The owner Stena Bulk has underlined there are no indications that the ship had breached any rules.
