A mysterious figure spotted on a rooftop as a second explosion went off near the finish line of the Boston Marathon has some wondering whether the perpetrator of the attack has been caught on camera.

The "mystery man"  appears to be walking on the edge of a rooftop, as if observing the explosions as they are happening. The photo of the man, uploaded to Twitter has gained a lot of attention on social media overnight.

Twitter user @DougieOliver called the photograph "the spookiest thing I have ever seen," while another user, @MartyWeiss, claimed that the man is standing on top of a block of rental units with access to a rooftop terrace.

The photo has captivated all platforms of social media and has been given to proper authorities to study. At this time, it remains undetermined if it is legit or a doctored photograph in some way.

It is important to note, while the mysterious figure could be entirely unrelated to the blasts, the Boston division of the FBI has asked anyone with any information or images that might contain any clues to contact them via 1-800-CALL-FBI.
