Italian antitrust agency AGCM has opened an investigation into Apple, alleging that the company disadvantages third-party developers with restrictive policies.
Apple is under another round of antitrust investigations, as Italy's antitrust watchdog has begun scrutinizing Apple's App Store policies concerning third-party developers.
AGCM also alleges that developers aren't given sufficient data about the success of their ad campaigns. The practice could force competitors away from distributing apps via the App Store, which could benefit Apple's first-party apps.
Apple could risk a fine of up to 10% of its annual turnover if it is found guilty of abuse of the market.
On Wednesday, European Union officials ramped up a probe into Apple. They believe that Apple's tight restrictions on the iPhone's built-in NFC chip to Apple Pay make it impossible for third-party companies to break into the mobile payment market.
In February, the US Department of Justice escalated its antitrust investigation against Apple as it seeks to determine if App Store rules are disadvantageous to competitors.
