The Malaysian Anti-Corruption Commission (MACC) has confirmed that former Finance Minister Lim Guan Eng has been arrested tonight.
MACC said a statement will be issued later, The Edge reported.
Earlier it was reported that Lim had arrived at the MACC headquarters here at 9.10pm while rumours swirled about his possible arrest over the Penang tunnel project.
The Star Online reported that Lim arrived in a white Vellfire.
According to The Star, scores of reporters had been camping out at the MACC since afternoon following talk that Lim, who is also the former Penang Chief Minister, would be arrested over the RM6.3 billion project.
Earlier, Umno-linked portal SuaraTV had written an article claiming that the Bagan MP was arrested around 9 pm, which has since been denied.
Lim was called to the MACC headquarters three times in July over investigation into fresh leads on the RM6.3 billion Penang undersea tunnel project.
Lim served as Penang chief minister from 2008 until 2018.
Graft investigators have so far questioned close to a dozen people over the case.
This includes Penang Chief Minister Chow Kon Yeow, and state exco members Jagdeep Singh Deo, Chong Eng and Phee Boon Poh.
MACC had also visited the offices of state Public Works, Utilities and Flood Mitigation Committee chairman, Zairil Khir Johari, and Deputy Chief Minister ll Dr P. Ramasamy.
It is believed that MACC is looking into allegations that the state government allowed the Penang Tunnel special purpose vehicle (SPV) company to pre-sell state land rights worth RM3 billion despite a four-year delay in the construction of roads.
Investigators are also believed to be looking into the feasibility and detailed design studies that have yet to be completed, even though payment of RM220mil was allegedly made to the SPV.
