The Syrian man shot dead by French police last week may have taken part in the sexual assaults in Cologne on New Year's Eve. ISIS supporter Walid Salihi, believed to be in his late teens or early 20s, was arrested in 2014 in Cologne for sexually abusing women in a night club.
Salihi is said to have 'rubbed the behinds of females' and touched their 'intimate parts,' according to a German police report.
A friend of Salihi was arrested after the Cologne mass attacks, where hundreds of women were sexually assaulted, leading to suspicion that he may have been part of the mob on New Years Eve before travelling to France, Bild newspaper reports.
Salihi was shot dead when he tried to enter the police station in Barbes, northern Paris, shouting 'Allahu Akbar' and threatening officers with a knife on the anniversary of the Charlie Hebdo attacks.
He was later found to have carried a fake bomb vest and a piece of paper where he pledged allegiance to ISIS. German authorities have confirmed the Salihi lived in a centre for asylum seekers in Recklinghausen, some 60 miles north of Cologne, where police found he used seven aliases.
'We don't know who the man really is,' said Uwe Jacob, director of the local state criminal office probing his background and movements in Europe.
