Actress Zooey Deschanel has received a formal apology after a U.S. Tv station ran a caption which falsely identified her as a suspect in the Boston Marathon bombing.

Executives of a Tv captioning service have reached out to the New Girl star to express their regret after the Kdfw station in Dallas, Texas ran a picture of accused suspect Dzokhar Tsarnaev with the words, "Marathon Bomber. He is 19-year-old Zooey Deschanel."

The mistake was made on Friday (19Apr13) during Tv coverage of a massive manhunt in Boston, Massachusetts for those responsible for the horrific blast on 15 April (13).

Deschanel was alerted to the issue and wrote in a post on, "Whoa! Epic closed captioning Fail!" and she has now received an apology from Kala J. Patterson, president of Caption Solutions, the company behind the blunder.

In a statement, Patterson insisted company "sincerely apologises for this error" and "deeply regret" the mistake.
