Madurai, Aug 10 (PTI): Expelled AIADMK leader Sasikala Pushpa and two of her family members have been booked by police on a complaint of alleged illegal detention and sexual harassment by her former domestic help, police said today.

All-Women Police in Pudukottai in Tuticorin District registered the case against the MP, her husband Lingeswara Thilagan and their son L Pradeep Raja based on a complaint by the woman who had worked along with her sister as domestic help in the house of Sasikala, when she was the Tuticorin Mayor from 2011 to 2014, they said.

The case was registered after the Tuticorin Superintendent of Police to whom the complaint was given forwarded it to the Pudukottai All-Women Police station.

The complainant alleged that she and her sister were detained and sexually harassed by the MP, her husband and their son, police said.

Pushpa, who reportedly slapped DMK MP Trichy Siva at Delhi airport recently, was expelled from AIADMK on August 1 by its supremo Jayalalithaa on grounds of violating party principles and ethics and bringing disrepute to the party.

On the same day, the MP alleged in the Rajya Sabha she was slapped by a "leader" and faced threat to her life in Tamil Nadu.

Last week, Pushpa's husband and her son had moved the Madras High Court claiming that a case had been registered against them by Anna Nagar Police in Chennai and sought anticipatory bail.

However, their petitions were disposed of by the court after the state government submitted that police had not filed the case as claimed by the petitioners.
