A 29-year-old man accused of stealing a bicycle in Boston's North End tried to complete his own version of a triathlon to get away from police.

Police say Jason Duncan of Somerville rode the bike onto the North Washington Street Bridge, jumped off the bridge into Boston Harbor and swam to shore when they tried to arrest him Tuesday night.

He then ran down a harbor walkway before being caught.

Suffolk County District Attorney's spokesman Jake Wark says Duncan pleaded not guilty Wednesday in Boston Municipal Court to one count of larceny over $250. Bail was set at $500.

A message left with Duncan's attorney was not immediately returned Wednesday.
