NEW DELHI (AFP) - Indian police on Friday detained two teenagers for allegedly killing a 51-year-old Uber driver in the capital New Delhi earlier this week, after an argument erupted in the car.

The "accused are 17-year-old minors and got into a heated argument with the driver soon after boarding the cab," Pushpendra Kumar, Deputy Commissioner of Delhi Police, told AFP.

Since both of the suspects are minors, they can't be formally arrested in accordance with Indian law. The police said a juvenile board will now decide what action should be taken against them.

The initial police investigation suggested that the argument could have started over directions or where to stop the car.

"The driver, Kuldeep, was shot twice, once each in the head and chest, and his body was dumped," Kumar added.

The body was discovered at a secluded spot in the city on Thursday, a day after the killing, by locals.

Police officials said that the accused were tracked with help from the cab company's software, which the duo had used to book their ride.

In a statement, Uber later said that it had "proactively shared details" to help the police investigation.

A Press Trust of India report said that Kuldeep is survived by his wife and three children.

Uber, the world's most valuable start-up, set up its India operation in September 2013 and now does business in more than 25 cities in the country.
