Congress member of Parliament Rahul Gandhi has sent a legal notice to US-based Web site www.hinduunity.org for alleged "perverted, scurrilous and gutter writing" against him and his family members.

Disclosing this on Friday night, party spokesman Abhishek Singhvi told reporters that the notice has been sent against an individual Rohit Vyasman and an entity called Ezboard Inc for allegedly launching a campaign against the Gandhi family.

The Web site was traced after weeks of efforts, he said and added, the legal notice was served to them threatening prosecution against them, including the "co-conspirators."

The legal notice has sought strictest action as per the law possible against them so that such writings were stopped.

"It is high time that civil society took note of this dirty campaign," Singhvi said adding, the e-mail, courier and post box number of those names are being searched to find out more details.

Singhvi parried a question about whether a first information report against all the persons would be filed. He merely said that all the options were open in this matter.

He also parried a question on whether the Web site would be blocked in view of its scurrilous campaign.
