A Thessaloniki prosecutor ordered an investigation on Tuesday into the construction of the northern city’s metro system, which has stalled again.
Work on the project stopped late last year as the relevant consortium, made up of Greek and Italian companies (AEGEK-Impregilo-Ansaldo-Seli-Ansaldobreda), asked for its contract with the state to be torn up.
The government had extended the agreement with the consortium to November 2016 after a series of obstacles, including archaeological fines, held up the project.
Anti-corruption prosecutor Argyris Dimopoulos is investigating whether there was a breach of trust at the expense of taxpayers.
He will also be investigating whether the public company managing the project, Attiko Metro, was responsible for the state suffering damages.
