“Louvre attack: Egyptian man, 29, believed to be assailant” http://www.bbc.com/news/world-europe-38863431
Prosecutor Molins said the Egyptian man had no identity papers but mobile phone data showed he had arrived in Paris on 26 January after acquiring a one-month tourist visa in Dubai.
However, he cautioned, the authorities have not yet formally established the suspect's identity.
Egyptian security sources though say they have identified him, Reuters news agency reports.
He was believed to have been staying in the capital's 8th district (arrondissement) which was searched in a police raid earlier on Friday.
There, he bought two machetes from a shop selling guns.
