Boulder police are continuing to investigate a robbery and assault that took place at 11 p.m. July 19 in the area of Comanche Drive and Inca Parkway and are hoping pictures of the suspects' clothing may help identify the men.

The male victim said he was riding his bike and stopped to make a phone call when he was attacked by two unknown men who pushed him off of his bike and began to punch and kick him.

The men were dressed in black and, according to the victim, were wearing ski masks to cover their faces. The victim said the suspects stole money, a backpack containing clothes and other personal items, and a knife. The victim told police the suspects threatened him with his own knife.

Both suspects are described as white or Hispanic males, in their early to mid-20s.

One man is described as 5-feet-5-inches tall and 115 to 125 pounds, the other as 5-feet-6-inches tall and 130 to 140 pounds. They were wearing distinctive clothing, including a hat with lighter caps attached on the back and a red flannel shirt.

Anyone with information is asked to call Detective Kurt Foster at 303-441-4329. To report information anonymously, call Northern Colorado Crime Stoppers at 1-800-222-TIPS or go to the website at www.crimeshurt.com.
