Grammy-winning singer Chris Brown is under investigation for an alleged assault in a West Hollywood parking lot, the Los Angeles County Sheriff's Department said early Monday.

"The altercation allegedly led to Chris Brown punching the victim," the department said.

The "victim" wasn't identified, but TMZ, which first reported the fight outside the Westlake Recording Studio, said it also involved Frank Ocean, one of the top nominees at the Grammy Awards next month.

In a Twitter posting later, Frank said he "got jumped by Chris and a couple guys" and suffered a finger cut.

It wasn't Chris' first problem in the run-up to the Grammys. His attack on singer Rihanna on the eve of the 2009 awards event overshadowed the show.

Last June, he was injured in a brawl with members of hip-hop star Drake's entourage at a New York nightclub.

No arrests were made. Brown was gone by the time deputies arrived, but the department said the investigation is ongoing and Brown would be contacted later.

Email messages to Frank's publicist and Chris' lawyer and representative were not immediately returned. A man answering the phone at the recording studio declined to comment.

Chris, 23, remains on probation for the attack on Rihanna and is due back in court on Feb. 6 to update a judge on his progress. Prosecutors have raised concerns about records showing that Chris has completed his community labor obligations.

He's the total package

Los Angeles police say actor Taye Diggs chased down and captured a burglary suspect he found rummaging through his garage.

It happened after the "Private Practice" star and his wife, Idina Menzel, returned to their Studio City home from the Screen Actors Guild Awards, where Taye was a presenter.

An LAPD spokesman said shortly before 11:30 p.m. Sunday, Taye saw a man in his garage, apparently looking for items to steal. The man ran off, but Taye ran down the street and held him for police. Neither man was hurt.

Twenty-year-old Hassan Juma was arrested and remains jailed Monday on $50,000 bail.

Looking forward to 2014

Barbara Walters would probably like to hit the reset button on 2013.

She's got the chickenpox and remains hospitalized more than a week after going in after falling and hitting her head at a pre-inaugural party in Washington on Jan. 19. A fellow host on the "The View," Whoopi Goldberg, said Monday that Barbara has been transferred to a New York hospital and hopes to go home soon.

The 83-year-old news veteran, who underwent heart surgery in May 2010, apparently avoided a disease that hits most people when they are children.

"We love you, we miss you," Whoppi said on "The View" in a message to the show's inventor. "We just don't want to hug you."
