Jerron Smith, 31, of Deerfield Beach, is the first person to be arrested for running afoul of the new law since it went on the books March 9, the Broward County Sheriff's Office said Monday.

A spokeswoman for the office said a SWAT team went to Smith's home Thursday and seized the AR-15 when he refused to surrender it voluntarily. The officers also seized a .22 caliber rifle he owned, hundreds of rounds of ammunition, a bump stock and numerous other weapon-related items.

The new gun regulations signed into law raise the age in Florida to buy a rifle to 21 and establish a three-day waiting period on gun purchases. They also include language allowing school employees and teachers to be armed. Another provision allows law enforcement to apply for a "risk protection order" from a judge to seize the guns of the mentally ill and anyone deemed a danger to the community.

Broward deputies sought the order in Smith's case after he was arrested March 29 on an attempted murder charge for allegedly firing six shots into the back of a car being driving by his best friend, Jackon Lavon, 34.
