The police, however, did not name Mr Dhinakaran in the final report and said that a supplementary charge sheet will be filed against him and other accused after it completes the probe against him.
The charge sheet was filed against Sukesh Chandrasekhar, who was arrested on April 16 and has been denied bail twice by the sessions court and then again by the Delhi High Court. Special Judge Manoj Jain listed the matter before the concerned judge on July 17.
A senior police official, associated with the case, said they had chargesheeted Mr Chandrasekhar for various alleged offences under the IPC including forgery of valuable security, forgery for purpose of cheating, using forged document as genuine and possessing a forged document and intending to use it as genuine.
If convicted, the offences carry a maximum sentence of life imprisonment.
Mr Chandrasekhar was arrested for allegedly taking money from Mr Dhinakaran to bribe Election Commission officials to get the AIADMK's two leaves symbol for Ms Sasikala's faction.
According to the Crime Branch of Delhi Police, they had seized a fake identity card of a Rajya Sabha Member of Parliament with security features from Mr Chandrashekhar.
Mr Dhinakaran, Mr Mallikarjuna, and suspected hawala operators Nathu Singh and Lalit Kumar are out on bail.
His faction had hoped to obtain the symbol for the bypoll to the RK Nagar Assembly seat in Tamil Nadu which was later cancelled by the EC after the alleged irregularities surfaced.
The bypoll was necessitated by the death of Tamil Nadu Chief Minister J Jayalalithaa who represented the constituency.
The EC had frozen AIADMK's symbol after the two factions of the party -- one led by Dhinakaran's aunt Sasikala and the other by former chief minister O Panneerselvam -- staked a claim to it.
Mallikarjuna was arrested for allegedly facilitating a Rs 50 crore deal between TTV Dhinakaran and Mr Chandrasekhar. Mr Dhinakaran has been accused of arranging the money from undisclosed sources and getting it transferred from Chennai to Delhi through illegal channels.
