Washington: The US-based lawyer of a Delhi woman executive who was allegedly raped by an Uber cab driver in December, Wednesday dismissed the addition of a panic button to the web-based US taxi firm's app in India as a 'marketing ploy'.

"Today's additions of a panic button and ride share notification to the Uber app in India are far cries from the safety measures riders need," New York-based lawyer Douglas H. Wigdor said in a statement on Twitter. "Most unfortunately, neither of these measures would have prevented the rape of our client and are yet another obvious marketing ploy to garner the support of the people of Delhi who deserve more," he said.
