In March 2024, the special prosecution office issued three arrest warrants for senior officials of the municipality of Tirana, Redi Molla, Mariglen Qato and Taulant Tusha (already in prison for the incinerator case), and requested the appearance to the judicial police of five other municipal officials and the administrator of a private company.

Most of the investigations into this case are closed and, in December 2024, the special prosecution office sent for trial on charges of corruption, money laundering and false declarations the former director of the public company Tirana Water Supply, Redi Molla, and the former head of territorial protection inspectorate, Mariglen Qato. Taulant Tusha, former director of public works department in Tirana municipality, is accused of breaching the equality of participants in public procurements, along with other officials Enton Punavija, Julian Zanaj, Albano Janku, Eglantina Zere and Debroah Keçi. Nestor Muhametllari, owner de jure and former administrator of the company‘5D Konstruksion, is accused of active corruption of public officials and money laundering. 5D Construction’s assets has been frozen and the entity is accused of active corruption and money laundering.

The scheme called 5D by its whistleblower Belind Këlliçi, a former candidate of the opposition DP party for mayor of Tirana in the 2023 local elections, relates to the alleged establishment of a private company by directors of the municipality who had placed other persons as owners on paper to avoid the law on conflict of interest. The company is alleged to have won dozens of public contracts in institutions run by its directors, initially under the name Igor Elektrik, then V.A.S. Konstruksion and finally 5D, which according to whistleblower Këlliçi, was linked to the implication that it was owned five directors of the Tirana municipality. The prosecution’s investigations found that there were in fact two directors of municipality that had ownership of 5D Construction, Redi Molla and Mariglen Qato, and they were allegedly helped by their colleagues to obtain the contracts.

According to the financial analysis of the prosecution's office, 5D Construction generated revenues worth €20 million from 2016 until 2022. Most of this came from public contracts related to institutions headed by Molla and Qato. As the institution’s heads, they allegedly issued orders to appoint the members of the procurement unit to evaluate the offers and signed the contract themselves.

The money obtained from public contracts was allegedly used to extort money from the company through fictitious invoices and to go as cash into the pockets of the real owners. Another part of the money obtained from public contracts was allegedly used in building residences in the capital, where the procedure of issuing the buildings permit’s was suggested by the court to be seen as a conflict of interest. In another episode, former directors of the municipality of Tirana allegedly became partners in a hotel business in the coastal city of Durrës, an investment that worth €15 million. They are also accused of taking the ‘special’ status from the Ministry of Tourism, which excludes the investors from most of local taxes and the profit tax.

Other suspected members of the scheme are accused of collaborating and favouring the 5D company in public bids. According to documents seized by the special prosecution office, it appears that in various institutions, the evaluation of offers was not done by officials but by 5D Construction’s employees and in many cases they allegedly communicated with its employees to find legal arguments on how to exclude other operators who had given the better offers from the competition.
