LONDON -- British television broadcast the first picture of Mohammed Emwazi as a student today, showing the man identified as the Islamic State “Jihadi John” killer with a mustache and goatee beard wearing a large Pittsburgh Pirates baseball cap.

And the Major League Baseball team is not happy.

Sky News broadcast a photograph of the 26-year-old wearing a black cap with a logo that resembled the P from the Pittsburgh Pirates, which it said was stored by the University of Westminster where he studied.

British media had previously only published a picture of Kuwaiti-born Emwazi as a smiling schoolboy.

Two U.S. government sources have told Reuters that Emwazi is Jihadi John, the black-clad militant seen brandishing a knife and speaking with an English accent in videos released by Islamic State (IS). He appeared on the short videos in which hostages including Americans, Britons and Syrians were decapitated.

The document obtained by Sky News also showed that Emwazi had completed a degree in information systems with business management.

A spokeswoman for the University of Westminster said it was investigating how the information had been obtained and declined further comment.

The Pirates were not happy to see him in their hat and released the following statement:

“The classic gold P stands for Pittsburgh and is worn by our players, coaches and fans with a great sense of pride. It is absolutely sickening to everyone within the Pirates organization, and to our great fans, to see this murderer wearing a Pirates cap in this old photo.”
