Daniel Mark Williams, the son of former Newfoundland and Labrador premier Danny Williams, has been charged with assaulting a security guard at a bar in Florida.

Williams, 35, was charged with simple battery, disorderly conduct and obstructing or resisting an officer without violence following an incident, the sheriff's office in Pinellas County says.

Williams was arrested by police at Treasure Island, a resort community near St. Petersburg, after an altercation at a sports bar.

The St. John's Telegram reported that Williams ran into trouble at the Gators Sports Bar, and refused to leave the bar when requested.

Lt. Armand Boudreau told the Telegram that Williams is accused of punching a security guard at the bar 10 times.

Williams paid $800 in a bond and was released within hours.

Police in Treasure Island told CBC News that the incident is not unusual. The allegations against Williams are not considered particularly serious, as they are misdemeanour charges.

Speaking with CBC News on Thursday, Williams said he could not comment on specific details of the case.

He said, though, that he was with close friends during a wedding trip to Florida, and that "the charges result from a misunderstanding with the bar staff."

He said he could not comment further until the issue is resolved.
