Officials are investigating whether this alleged incident is connected to other similar incidents.
Browne is charged with Impersonating A Police Officer, Breach of Peace, Interfering With A Police Officer and Possession of a Dangerous Weapon in a Motor Vehicle.
He was released on a $50,000 bail and is due back in court later this month.
Former Senator Brown released a statement on his Facebook page referring to Browne as his “estranged half brother,” saying he only knows what has been reported in the news.
“As you many of you know, my mom and my late father were married and divorced 4 times each. Unfortunately, we were not close as a family,” Brown said in the statement. “These are serious charges and he will need to answer them. I feel badly for his children and I am thankful that no one was injured.”
It is not clear why Browne spells his name differently than the former senator.
