US Secretary of State Hillary Clinton should act on the case of an Indian diplomat's daughter who is suing New York city for a whopping $1.5 million for false arrest to avoid retaliation from other countries, said lawyer Ravi Batra.

Batra, lawyer of Krittika Biswas, sent a letter to Hillary Clinton June 1 that said: "I urge you to act and avoid possible retaliatory-reciprocity from foreign nations."
