A Bellmore man is under arrest for allegedly posing as a special agent for the government.
Richard Derosa is accused of trying to set up a meeting to buy a handgun last year.
According to police, Derosa met up with the seller in a McDonald's parking lot in upstate New York after claiming he was a federal agent.
A search of his home allegedly turned up several guns and fake badges.
Derosa was arrested this week and remains in jail.
