He was dressed as Spider-Man, but he did not try to uphold the law like his fictional comic book counterpart. Instead, he broke it by snatching a paper bag filled with more than $6,000 in cash and credit card information, a Los Angeles Police Department spokeswoman said.

But who was that masked man on a Hollywood, Calif., street? With so many people in the area in the habit of dressing as Spidey, that's the question police said they were trying to answer.

"We are still pursuing some leads on that incident, and it is still an active investigation," LAPD Capt. Beatrice Girmala told ABCNews.com. "There is more than one Spider-Man out there, so we are questioning them all."

Girmala said the suspect took the bag from an employee of the Starline Tours bus company Friday morning as a worker was leaving the company's Hollywood Boulevard headquarters.

Starline Tours, the oldest and largest sightseeing tour company in Los Angeles, did not return calls to ABC News.

Spider-Man is a character of Marvel Entertainment, which is owned by Disney, parent company of ABC News.
