Junior defensive back Ishmael Adams was arrested on campus for robbery, according to sources.
The bail was set at $100,000.
UCLA released a statement: "We are aware of the situation and continuing to gather information. As this is a pending legal matter, we will have no further comment at this time."
One story circulating is that Adams tried to steal the cellphone of an Uber driver.
Adam is UCLA's starting nickel back and one of the best punt and kick returners in the nation.
