Liverpool has apologized to fan Sean Cummings - creator of the fictional Twitter character Duncan Jenkins - for his "inappropriate" treatment by the club's director of communications Jen Chang.

Cummins, who dreamed up the popular spoof football journalist, met Chang in a Manchester restaurant after the latter suspected someone from inside the club was leaking information.

At that meeting Cummins assured Chang his source was actually second-hand details gleaned from the internet, however, he subsequently alleged in a blog Liverpool 's communication chief had made a number of threats to him.

The club investigated the matter and Cummins has received a letter of apology from managing director Ian Ayre.

"Based on everything I have heard and seen, including information provided by the parties involved in the matter, I acknowledge some of the elements you highlight were not appropriate," said the letter, published by sportingintelligence.

"I would therefore like to apologize to you on behalf of Liverpool FC , for any upset and distress this caused you.

"Clearly it is not appropriate for me to comment on how the club is managing this internally, and I trust you understand this."

The club are making no further comment on the matter.
