FBI reveals surveillance of friend of Tsarnaevs

Says cab driver knew he was being tracked, complied with requests

The FBI launched intensive surveillance of a friend of the suspected Boston Marathon bombers last year, tracking him by car through the area and at one point urging him to stay away from Boston on the Fourth of July, authorities said Wednesday.

FBI agents were under orders to “make sure they stay with Mr. [Khairullozhon] Matanov, and don’t lose him,” FBI Special Agent Timothy McElroy told US Magistrate Judge Marianne B. Bowler in court. He said that Matanov knew about the surveillance and that “it was not covert in any manner.”
