Nitish Thakur was intercepted yesterday when he was about to board a flight to Nepal, the official said.
The former MHADA official was sent back home and the ACB is keeping a close watch on him, he added.
The Maharashtra ACB plans to move the court in Alibaug in neighbouring Raigadh district, seeking stern action against Thakur, who was granted bail after setting a condition that he should not leave the country till the case was decided.
As the money laundering activities surfaced during the probe, a case was registered against him by the Enforcement Directorate (ED) under the Prevention of Money Laundering Act.
Thakur's anticipatory bail in connection with the case was also rejected by the Bombay High Court.
However, upon a request the High Court granted him permission to appeal against the order in the Supreme Court within three weeks.
