German authorities say an autopsy confirms that a 22-year-old Syrian man who was believed to have been plotting a bombing attack killed himself in his jail cell in Leipzig.

Leipzig prosecutor Ricardo Schulz told the dpa news agency Friday the autopsy showed Jaber Albakr died by strangulating himself with his T-shirt. He says "as a result of the investigation, so far the Leipzig prosecutors' office believes the deceased committed suicide."

Saxony officials have been widely criticized for their handling of the case, from initially letting Albakr elude them as they prepared to raid the apartment where he was staying to allowing him to take his own life.

Interior Minister Thomas de Maiziere on Friday again stressed "those responsible know there is still a lot of work ahead of them."
