According to Tampa police, Walker was thrown out of Prana, 1619 East 7th Avenue just after 2:00 a.m. After he was tossed from the club, Walker allegedly began yelling at some of Prana's staff members and then charged into four employees. A police officer sprayed Walker with pepper spray to halt his attack.
Walker was released on his own recognizance.
"I am extremely sorry that my actions may bring any embarrassment to my coaches, teammates or our organization," Walker said in a statement Saturday released on Saturday afternoon.
Three Bucs players have had brushes with the law over the last seven months.
Bucs cornerback Dwight Smith was arrested on April 16 and charged with aggravated assault, which is a third-degree felony, after he allegedly waved a gun at a motorist during a road rage incident.
Last October, Tampa Bay starting right guard Cosey Coleman was arrested and charged with beating the mother of his eight-month-old son outside a day care center.
The Bucs said they would wait to address the arrests of Coleman and Smith until the courts handed down final judgements. The team will likely handle Walker's situation in a similar manner.
"Until this matter progresses through the legal system, it is not appropriate to comment on this situation at this time," said Bucs general manager Rich McKay.
