A large police presence was on hand for Sunday's annual Five Boro Bike Tour as approximately 32,000 cyclists made their way along the 40-mile route through New York City.
For the first time riders were not allowed to wear backpacks, though fanny packs and some other small bags were allowed. The new rules came in the wake of the Boston Marathon bombing where explosives were concealed in backpacks.
Police say officers on bikes and scooters will be riding alongside tour participants. Mobile cameras, radiation detectors and counterterrorism teams have also been deployed. Harbor officers will escort ferries going to and from Staten Island, where the tour ends.
