German security officials said Tuesday they made more than 750 arrests and seized large amounts of drugs after gaining access to extensive chat data of encrypted cellphones.

The focus of the investigation, which started in April 2020, was on data from users of the provider EncroChat who were involved in the illegal drug trade, Frankfurt prosecutors and the country’s Federal Crime Police Office said in a written statement.

Dutch and French officials helped with the investigation, prosecutors said.
