Here is the real reason as explained by Adeyanju Deji.

Dear Nigerians follow THREAD: Innoson Motors took a loan with @gtbank. They over deducted by over 700m. He took them to court. Court ordered them to pay 2.8B based on accumulated interest. They went to appeal and lost on appeal. They are at the Supreme Court. The accumulated fee as at today stands at over 6B. @gtbank has been bribing officials to evade paying.

Then there is another judgement he got against Nigeria customs for selling his goods illegally. @gtbank was also supposed to pay. They have appealed. Instead of obey the courts, @gtbank resorts to intimidation & frustrating Innoson.
@gtbank mobilized dozens of policemen to pick him up but he is resisting arrest so far with the help of locals in his home in Enugu. Innoson Motors is doing a lot for Nigeria but we are in a country where if the cabals of the day don’t like your face, you must go down. Oh Nigeria, shame of a nation
