Watch Magdeburg attack suspect's 2019 interview with the BBC
Five years ago, Taleb al-Abdulmohsen sat down for an interview with the BBC where he discussed a website he designed to help ex-Muslims flee the Gulf region.
Abdulmohsen had lived and worked in Saudi Arabia before claiming asylum in Germany.
He's now accused of driving a car into a crowded Christmas market in Magdeburg, Germany, killing five people and injuring more than 200.
Prosecutors expect to charge him with murder and attempted murder soon, according to the head of the local prosecutor's office.
