36Naija News reports that the 64-second video about the attack had gone viral on the internet on Saturday.
In the video, Ekweremadu was violently questioned over his alleged conspiracy with the Federal Government of Nigeria to proscribe the IPOB in the South Eastern region of Nigeria and killing several of its followers.
The Senator who also gave an account of the event on his social media handle, @iamekweremdu, has assured that he was safe.
He went on to condemn the attack and said that he had reported it to the Nigerian Ambassador to Germany, Mr Yusuf Tuggar.
He said: “I attended the Second Annual Cultural Festival and Convention organised by Ndi-Igbo Germany in Nurnberg today where I was billed to give a keynote address along with the President-General of Ohanaeze Ndigbo, Chief Nnia Nwodo, who, however, could not make it eventually.
“I was given a resounding welcome by Ndigbo in Germany and everything went smoothly until some men, who identified themselves as IPOB members stormed the venue and began to complain about the killings in the South East, stressing that there would be no Igbo event at the venue.
“I tried to engage them, but when they became unruly, I had to leave the venue. The organisers also invited the police and I was accompanied out of the venue.
“Much as I am disappointed in their conduct, especially as I am one of the persons, who have spoken up on justice for Ndigbo, the Python Dance, judicial killings in Igbo land and elsewhere both on the floor of the Senate and in my written and personal engagements with the Presidency and the media as well as rallied the South-East Senate Caucus to secure Mazi Nnamdi Kanu’s release with Senator Enyinnaya Abaribe taking him on bail to douse tension in the South East, I nevertheless do not hold this to heart against them, for they know not what they do.
“I have received thousands of solidarity calls and messages from well-meaning Ndigbo. I want to assure them that I am hail and hearty. I have also spoken with the Nigerian Ambassador to Germany, Ambassador Yusuf Tuggar.”
