EFCC had already invited Mrs Ganduje to report to the EFCC’s Abuja headquarters on September 13 but she did not appear and the EFCC then threatened to arrest her. Sources close to her later said she travelled to the UK at the time to attend the graduation ceremony of her son.

Investigators are questioning Mrs Ganduje over allegations relating to land fraud in a petition by her own son, Abdualzeez Ganduje.

A person, who has the knowledge of the arrest but asked not to be identified, said “she was arrested this (Monday) evening.”

Mrs Ganduje was still at EFCC headquarters as of 6 a.m. on Monday, this newspaper learnt.

It will be noted that it is her son; Abdulazeez that dragged his mum, Hafsat Ganduje, to the EFCC, sources familiar with the matter said, suggesting a pattern of corruptly using family access to power for private enrichment.
