HOOKSETT, N.H. —The owner of Riley's Sport Shop in Hooksett has apologized for his actions during a gun rally that ended with another man in handcuffs.

As police tried to make the arrest a struggle ensued, and Riley's owner Ralph Demicco kicked a set of keys that had fallen out of an officer's pocket. Video also shows Demicco leaning in and yelling expletives.

In a letter to Concord Police Chief John Duval, Demicco admitted to doing that, and said he regrets it. He called his actions deeply inappropriate.

"It created a situation that I had grave concerns for my officer's safety and quite honestly, the others who were there, who were protesting and doing so lawfully," Duval said of the incident.

The Concord Police Department does business will Riley's, but the chief did not comment on whether anything will change.
