Dutch police say Telegram can request phone numbers that users actually want to keep secret. This possibility contradicts the chat app's promise to users.

This appears from documents released by the police force management after an appeal to the Open Government Act, reports BNR. The released documents contain instructions that allow police officers to "urgently" requisition IP addresses and phone numbers from Telegram.

"Requests are eligible if there is immediate imminent danger to life," writes a police official. The instructions were distributed last December. They included a form with the messaging service's logo.

Telegram says it values users' privacy and even claims in its privacy policy to have "never" shared personal data with law enforcement officials. That promise has been in question for some time. The German Federal Criminal Police Office (Bundeskriminalamt) already revealed last year that it had successfully requested personal data from the messaging service.
