Denver police are asking for the public’s help in identifying the hundreds of motorcyclists who rode together through the metro area Sunday, strangling traffic downtown and on Interstate 25.

Investigators say the group “at times disregard(ed) traffic laws and compromis(ed) public safety.”

At one point, police say, they stopped and blocked all lanes of traffic on northbound I-25 near University Boulevard. The group was also seen disregarding red lights downtown and weaving in and out of cars on a crowded Park Avenue as fans headed to a Rockies game.

Anyone with information on the motorcyclists are asked to call 720-913-7867 or send video to Crimestoppers@denvergov.org. Tipsters can remain anonymous and are eligible for a reward of up to $2,000.
