The Economic and Financial Crimes Commission apprehended Olakunle Oluomo, Speaker of the Ogun State House of Assembly, at Muritala Muhammad Airport in Lagos State.
Oluomo was arrested over allegations bordering on financial crimes.
A staff member at the assembly who pleaded anonymity said the speaker was picked up this morning at the Murtala Mohammed Airport, Ikeja, Lagos, by operatives following a tip-off.
According to sources, Oluomo was undergoing further grilling in the custody of the agency.
He was said to have been on the wanted list of the commission following his failure to honour EFCC invitation several times.
He and some others were accused of forging signatures and financial documents of the assembly.
An attempt to get confirmation from the EFCC failed as the spokesperson for Lagos zonal office, Ayo Oyewole, refused to answer the calls.
