Mr Saraki had indicated that he would not report to the police as directed in a letter by the Inspector-General, Ibrahim Idris.
He said this in his response to the police chief dated July 24.
In it, the Senate president said he was aware President Muhammadu Buhari had directed the police to obtain written statement from Mr Saraki or send personnel to question him if he is needed for questioning.
Police had earlier summoned him to appear on Tuesday morning at 8.00a.m.
But security operatives later blockaded Mr Saraki’s convoy on Tuesday morning as well as the home of Deputy Senate President, Ike Ekweremadu.
Many believe the siege was to prevent both presiding officers from reaching the Senate; prevent a mass defection of APC lawmakers and also allow for their replacement by senators loyal to President Buhari.
Mr Saraki eventually appeared at the Senate where he presided over the defection of 14 senators from the ruling APC.
The police later on Tuesday frowned at Mr Saraki’s failure to appear as directed and threatened to enforce his appearance.
According to a tweet by Special Assistant on New Media to the president of the Senate, Olu Onemola, Mr Saraki met with the investigators at about 1.40pm today.
“Further to the invitation to the Senate President, Dr. Abubakar Bukola Saraki, by the Police on July 23, 2018, and his written response to them on July 24, 2018 on why he could not see them that day — today at about 1:40pm, the Senate President met with a team of investigators on the Offa Robbery case in his office.
“Dr. Saraki used the opportunity to reiterate that he has nothing to do with either the robbery incident on April 5, 2018, or any other criminal activity,” he tweeted.
Another source from the National Assembly, who asked not to be mentioned said the interview was to get additional information on his statements.
