Rhea poisoned Sushant, killed him, claims the actor's father

The allegations have come a day after the Narcotics Control Bureau (NCB) registered a case against Rhea and a few others.

The central anti-drug agency is probing an alleged drug abuse angle in this case, after chat records from Rhea's phone suggested so.

A team of the agency is currently on its way to Mumbai, per reports.

The NCB has reportedly filed the case under sections related to "possessing, purchasing and using cannabis," and "abetment and criminal conspiracy to commit an offense."

Rhea's phone chats hinted that she had been in touch with drug dealers.

However, the 28-year-old actor's lawyer has denied the allegations, claiming that she has never consumed drugs and is "ready for a blood test."

In another development, reports suggest that Siddharth Pithani, Sushant's flatmate and a key witness in the case, has told the Central Bureau of Investigation that eight hard drives were destroyed on June 8, the day Rhea moved out of Sushant's house.

Notably, CBI started investigating this case after a Supreme Court order last week. It also questioned Sushant's staff members Neeraj and Samuel Miranda.

CBI officials today questioned Rhea's brother, Showik Chakraborty, at the DRDO guesthouse where they have been staying. They are expected to soon summon Rhea for questioning.

Separately, the Enforcement Directorate (ED), which is probing a money laundering case in connection with Sushant's death, has summoned Rhea's father, Indrajit Chakraborty for questioning. It had on Wednesday questioned Rhea's talent manager Jaya Saha.

Sushant was found dead at his residence in Mumbai on June 14.

The Mumbai Police had said he died by suicide and was suffering from clinical depression and bipolar disorder.

However, his family said they knew nothing about Sushant's alleged mental illnesses.

Rhea is accused of financial fraud and abetting the alleged suicide of Sushant.
