The permission of Trinity Network Services Limited, where Oladipupo was sole principal and controller, has also been cancelled.
During an FSA investigation into his conduct in November and December 2008, Oladipupo failed to attend a compulsory interview and provide the FSA with requested documents and information.
As a result of his failure to deal with the FSA in an open and co-operative way, the FSA deemed that Oladipupo was not fit and proper to hold a regulated position, and therefore removed his approval.
The FSA also cancelled Trinity’s permission for not having competent and prudent management, as a result of Oladipupo’s approval being withdrawn.
FSA head of retail enforcement Tom Spender said: “Approved persons and authorised firms must deal with the FSA in an open and co-operative way. Failure to comply with a request for information or to attend an FSA interview is unacceptable, especially when we are seeking to look into issues of potential concern.
“We will not tolerate such behaviour and will take tough action to remove the approval and authorisation of individuals and firms who attempt to prevent us from doing our job.”
