Lagoons CEO Abdulsalam Almarri among those quizzed as probe continues.
Four senior employees of state-owned developer Sama Dubai have been arrested and are being questioned by public prosecution, the latest in a string of executives caught up in the Dubai government's crackdown on corporate corruption.
One of those being questioned is Abdulsalam Almarri, CEO of the Lagoons project, newswire Zawya Dow Jones reported on Thursday, citing documents it has seen.
According to Zawya Dow Jones all four have been detained on allegations of bribery and mistrust.
Sama Dubai was not available for comment when contacted by Arabian Business.
The arrests at Sama come just a week after Nakheel confirmed one of its employees is being quizzed over bribery allegations and Tamweel's biggest shareholder Istithmar World said the mortgage lender's former chief executive and head of investments have also been detained.
The Dubai government has embarked on a massive drive to stamp out corruption in region's financial hub, with the public prosecutor earlier this week reiterating the government's strict stance and warning it will take action against violators.
Investigations are also underway into ex-employees of Deyaar Development, including its former CEO, and Dubai Islamic Bank.
