PHILADELPHIA — Philadelphia police say they’re looking into cellphone video reports of a man riding a big-wheeled tricycle down one of the city’s busiest boulevards.

Motorists tell WCAU-TV ( ) they saw the man pedaling down the middle of Roosevelt Boulevard on Sunday.

Motorists including Akeem Edwards tell the station the tricycle was holding up traffic as cars gingerly drove around the pedaling man.

Edwards says the man riding the tricycle “looked at me and smiled as he was rolling by.”

Police are trying to figure out who the man is, what he was up to and whether he might be cited for the incident.
