Greenwich police tell the Greenwich Time newspaper that they arrested the guard, 50-year-old Joseph Babnik of Carmel, N.Y., on Thursday. He was given a misdemeanor summons on a disorderly conduct charge.
The 39-year-old Seymour and her estranged husband, wealthy newsprint magnate Peter Brant, are divorcing. Police say Babnik is watching the estate while the 62-year-old Brant is out of the country.
The couple have been living in different houses on the estate.
Babnik told police that Seymour had taken a slip of paper from him and he was trying to get it back. He says he fell into the door while trying to stop her from entering.
