In a statement to the Daily Beast, Deputy Chief Prosecutor Jenny Karlsson confirmed that the pilot “is still a suspect.”

“A Delta Air Lines pilot was arrested on July 22, on probable cause suspected of drunken driving at Arlanda Airport. After interviewing the suspect and other people who made observations in connection with the incident, the arrest was lifted on July 23 at 00:58 by a duty prosecutor,” she explained.

“However, the pilot is still a suspect and an investigation is ongoing. No other information can be provided at this time due to the confidentiality of the investigation in the case.”
