LOS ANGELES (AP) — UCLA starting cornerback Ishmael Adams has been arrested on suspicion of felony robbery after allegedly taking a phone from an Uber driver early Sunday morning.

UCLA's media relations office confirmed Adams' arrest Monday while the 13th-ranked Bruins were beginning preparations for their season opener Saturday against Virginia at the Rose Bowl.

Adams allegedly used force to take the phone, according to Tod Tamberg, the assistant director of UCLA's media relations and public outreach office.

The 21-year-old Adams is being held on $100,000 bail. He is scheduled to appear in court Tuesday afternoon.

Adams started all 26 games for the Bruins over the previous two seasons, returning two interceptions for touchdowns last year. He was the only UCLA player on either side of the ball to be named to the All-Pac-12 first team in 2014.

The redshirt junior from Woodland Hills, California, also returns kickoffs and punts for UCLA, making a 100-yard kickoff return for a touchdown last season against Arizona State.

"We are aware of the situation and continuing to gather information," UCLA football spokesman Josh Rupprecht said in a statement. "As this is a pending legal matter, we will have no further comment at this time."

Adams was one of the nation's top cornerback recruits when he arrived in Westwood in 2012. He is the son of Stefon Adams, who played five NFL seasons from 1986-90 as a defensive back for the Los Angeles Raiders, Cleveland and Miami.

Adams' teammates were surprised to learn about his arrest Monday as they began game-week preparations for coach Jim Mora's fourth season. Adams was expected to be a key component of their defense again this year, either as a cornerback or a starting fifth defensive back.

"Whoa, that's the first time I've heard of it," said a shocked UCLA running back Paul Perkins, the Pac-12's rushing leader last season. "I didn't know about it."
