Birmingham police are looking into the March 21 incident at the Townsend Hotel, Police Chief Richard Patterson told The Associated Press on Friday.

"We've got an altercation we're investigating," Patterson said. "It's not a high-priority item, sounds like a very simple altercation. There is still some investigation to do."

It was not immediately known whether any complaints were filed.

Officials at the Townsend would not comment.

Gilbert is chair and founder of Quicken Loans, which is based in Livonia, Mich.

Hall is a former vice president of Rock Financial, a part of Quicken. For a number of years, Hall was the public face and pitchman for the company, appearing in television and radio ads. Many of those ads involved the company's sponsorship of the Detroit Pistons.

His employment with Rock Financial ended in 2007. He now runs a Birmingham-based marketing and consulting company called DHall Ventures.

There is no phone listing for the company. Hall did not immediately return e-mail messages sent by The Associated Press seeking comment.

Quicken Loans officials declined to comment Friday about the altercation, spokeswoman Elizabeth Jones said.

Gilbert and the Cavaliers also declined to comment.

The leading investor of a group that bought the Cavaliers in 2005, Gilbert has at times been outspoken as the team's majority owner.

In September, he called rampant speculation that star forward LeBron James will leave Cleveland after his contract expires in 2010 "an insult to the city."

Last month, Gilbert expressed dismay when Cavaliers' guard Mo Williams was left off the All-Star team, poking fun at the snub by using made-up words like "stupidiculous," "idillogical" and "preposterageous" to describe his feelings.

Williams was later added to the roster as a replacement for injured Toronto Raptors forward Chris Bosh.
