On Wednesday, police had their first opportunity to speak with the 22-year-old cleaning woman, who has been recuperating in hospital since the January 15th incident, which left the train lodged in a house in the upscale suburb of Saltsjöbaden.
However, the first interview failed to shed any light on how the train may have started, with the cleaner telling police she has no recollection of what happened, TV4 news reported.
Police spokesman Lars Byström refused to divulge what the cleaner may have said.
“We held an interview with her today. But it would be inappropriate if I were to comment on what was said,” he told the Aftonbladet newspaper.
The cleaner was initially given the blame for the crash, with both Stockholm public transit operator SL and subcontractor Arriva accusing her of having stolen the train.
Both organizations have since apologized for unfairly portraying the cleaner as responsible for the incident, but the union representing her has said it is nevertheless considering filing a lawsuit over the matter.
Prosecutors investigating the incident have also uncovered a number of possible workplace safety violations which may have contributed to setting the train in motion.
