The “Uber rape case,” as it is known in Delhi, elicited widespread concern over the dangers of ride-hailing services in a country like India, where there have been a number of prominent rape cases in recent years, and in cities like New Delhi, where women have difficulty finding safe transportation after dark.

The government banned Uber in the Delhi region after the case came to light, but Uber and other ride-hailing services resumed operating in what the company has called “regulatory ambiguity.”

The criminal case against Mr. Yadav was delayed in March when the Delhi high court granted Mr. Yadav’s appeal calling for 13 witnesses, including the victim, to be re-examined. But the Supreme Court immediately stayed that order, then struck it down in September, the Press Trust of India reported.

The victim withdrew a lawsuit against Uber in California in September.

When the episode in December occurred, Mr. Yadav was free on bail in connection with at least three other serious criminal cases, including one of rape, in the state of Uttar Pradesh, and his employment by Uber drew sharp public criticism of the company, which was accused of not doing enough to ensure the safety of its passengers. The Delhi police are investigating whether Uber was criminally negligent in the December case, a senior police official, Brijendra Kumar Yadav, said Tuesday.

In January, Uber announced that it would start background checks in India. In a statement on Tuesday, the president of Uber India, Amit Jain, hailed the verdict against Mr. Yadav.
