Manchester City chief executive Garry Cook is being investigated by the club after being accused of ridiculing a player's cancer-stricken mother.
Defender Nedum Onuoha's mother claimed in Monday's edition of The Sun newspaper that she received an email from Cook which mocked her use of the phrase ''ravaged with it'' in her original message, referring to her cancer.
While Dr. Anthonia Onuoha received the reply, it was addressed to ''Brian.'' City's football administrator Brian Marwood was also among the recipients of Dr. Onuoha's original email.
Dr. Onuoha is only now complaining about the email sent in October 2010.
City said: ''Following allegations made to the football club by Dr. Anthonia Onuoha, subsequently reported in today's media, the club can confirm that a board-led review has been launched into the matter.''
