What evidence stood against Fogg as a bank robber?

The evidence standing against Phileas included his physical resemblance to the description provided to the police, his solitary ways, and his sudden departure.

The polished gentleman disappeared to give place to the bank robber. His photograph, which was hung with those of the rest of the members at the Reform Club, was
minutely examined, and it betrayed, feature by feature, the description of the robber which had been provided to the police. The mysterious habits of Phileas Fogg were recalled; his solitary ways, his sudden departure; and it seemed clear that, in undertaking a tour round the world on the pretext of a wager, he had had no other end in view than to elude the detectives, and throw them off his track.
