The State Prosecution will file an indictment against Dudu Topaz to the Petah Tikva District Court on Monday, charging the entertainer with possession and abuse of dangerous drugs.
Over the last three years, Topaz bought cocaine from Ophir Sasportas, the indictment states.
Sasportas is also expected to be indicted Monday over his role in mediating between Topaz and the goons who the disgraced television entertainer allegedly ordered to attack Avi Nir, director-general of the Keshet network.
Another suspect in the Topaz attacks case, Roman Aliyev, will be charged with trying to assault actors' agent Boaz Ben-Zion.
The last suspect in the Topaz case, Aliyev's accomplice Muhammad Yunis, gave himself up to police on Sunday.
