GREELEY, Colo. (AP) _ Bernard Bickerstaff Jr., the son of Denver Nuggets coach and president Bernie Bickerstaff, was arrested in connection with an armed robbery at a motel, Greeley police said Thursday.

The younger Bickerstaff, a former student at the University of Northern Colorado, was being held for investigation of aggravated robbery, police Sgt. John Gates said.

The junior Bickerstaff was a freshman member of the school's basketball team last season. He is not enrolled this semester.

Gates said Bickerstaff was arrested after a second suspect in the case was picked up in La Junta. Michael McKnight was held on an arrest warrant issued by Greeley police.

Police said the two men are suspects in an early morning robbery March 6 in which one of the men held a knife while robbing a night clerk.

Gates said the amount taken was ``fairly small'' and there were no injuries.

The elder Bickerstaff and Nuggets officials did not return phone calls left at their Chicago hotel, where the team was to play the Bulls on Friday night.

In January, UNC police sought the younger Bickerstaff as a possible witness in a campus burglary.

UNC Police Chief Terry Urista said he thought Bickerstaff's son, then a freshman at UNC, may have had information about the burglary, which occurred Dec. 8 at Turner Hall.

Urista said 80 compact discs and a disc case were taken from a dorm room, which was left unlocked while the residents took a final exam because one of the roommates reportedly had lost her keys.

Urista said his office contacted several stores that buy used CDs and asked them to be on the lookout for the stolen items. A few days later, an employee at a music and video store called UNC police and said two men were selling CDs that matched the description of the stolen items.

The clerk at the store identified the younger Bickerstaff from a photo lineup as the man who was with the suspect selling the CDs, Urista said.

Urista said Bickerstaff wasn't considered a primary suspect.
