Apple has taken down an app that uses crowdsourcing to flag sightings of U.S. immigration agents, apparently after being pressured by U.S. authorities. ICEBlock, a free iPhone-only app that allowed users to anonymously report and monitor the activities of Immigration and Customs Enforcement (ICE) officers, was no longer available on Apple’s App Store as of Friday.

The developer announced the removal on social media, indicating that the app was deemed to contain 'objectionable content.' They suspect that the removal was influenced by the Trump administration. The developer stated, 'We have responded and we’ll fight this!'

Despite the app's removal, existing users will still have access to it. The app previously boasted over 1 million users. Apple has not yet provided a detailed comment but stated that they aim to keep the App Store a safe space based on law enforcement concerns.

The decision follows a noticeable uptick in downloads for ICEBlock amidst recent escalated immigration enforcement, including surprise raids by ICE agents. Authorities had raised alarms after the app was allegedly linked to threats against ICE facilities, including a shooting incident in Dallas, where the gunman had reportedly searched for apps like ICEBlock.
