Police in Germany say they have begun investigation proceedings against four people in connection with the assault on Nigeria’s former deputy Senate President Ike Ekweremadu.
Mr Ekweremadu was attacked on Saturday at an annual Igbo cultural festival in Nuremberg, Germany.
The police confirmed the politician was escorted back to his vehicle where eggs were thrown at his vehicle.
In a Facebook post, Mr Ekweremadu said his attackers were members of Indigenous People of Biafra (Ipob).
According to him, the men “began to complain about the killings in the South East, stressing that there would be no Igbo event at the venue” before assaulting him.
He said that despite being “disappointed”, he did not “hold this to heart against them”.
The Igbo community is one of the largest in Africa and in Nigeria represents 24% of the population.
Ipob is a movement pushing for the declaration of an independent state for the Biafra people.
