Jansson, 23, from western Sweden, vanished on April 12th sparking concern from her friends and family, who come over to England to aid with the search.
After a nationwide appeal to track her down the Metropolitan police confirmed on Saturday that Jansson had been found unharmed.
"She is fine. We haven't spoken to her much but she hasn't had to go to the hospital," Matt Russell of the Metropolitan police told Aftonbladet.
Concern for Jansson's welfare became more apparent when neither the girl's family or friends had heard from her for days. She had last been spotted on Ilford high road, greater London, at 9:30am on April 12th.
