Police in New York are investigating a weekend (10Jul11) break-in at Broadway's Ed Sullivan Theater, where David Letterman hosts his late show.
The authorities were alerted to a possible burglary at the fabled venue, where the Beatles made their historic U.S. TV debut, early on Sunday.
Reports suggest the intruder pried open a metal bar on the glass doors at the entrance to the Manhattan theatre.
At press time, no arrests had been made and it remains unclear what, if anything, was stolen.
