Officer accompanying Brabantio

When Brabantio went looking for Othello, he brought along some officers to arrest him, but when Othello tells Brabantio that he has to go to the Senate on business, one of the officers says, "'Tis true, most worthy signior; / The duke's in council and your noble self, / I am sure, is sent for" (1.2.91-93).
