Another challenge to Apple.
This time in India.
The tech giant is facing an antitrust challenge for allegedly abusing its position in the apps market.
By forcing developers to use its proprietary in-app purchase system.
That's according to a source and documents seen by Reuters.
The allegations are similar to a case Apple faces in the European Union.
Regulators there last year started an investigation into the firm's imposition of an in-app fee of 30%.
The Apple case in India comes just as South Korea's parliament this week approved a bill dubbed "the anti-Google law".
It bans major app store operators like Alphabet's Google and Apple from forcing software developers to use their payment systems.
The Indian case was filed by a non-profit group which argues Apple's fee hurts competition.
Details of cases filed with the Competition Commission of India, or CCI, are not made public.
Apple and the CCI did not respond to a request for comment.
In India, Apple's iOS powered just 2% of the 520 million smartphones there by end-2020.
But experts say the U.S. giant's customer base in the country has more than doubled in the last five years.
Companies like Apple and Google say their fee covers the security and marketing benefits their app stores provide.
In recent weeks Apple has loosened some of the restrictions for developers globally.
