Have you seen this man?

Cambridge police just released this photo of the man who quietly robbed the Harvard University Employees Credit Union last week by presenting a letter to the teller.

According to Alexa Manocchio, Cambridge police public information officer, although CPD pulled over a bus last Wednesday, no arrest was made, and HUPD has been determined as the lead investigation agency on this case. HUPD spokesman Steven G. Catalano said that the investigation is still ongoing and open, and thus he declined to comment.

Perhaps someone should write a letter asking the man: "Please, Mr. Robber, give our money back?"
