However, the attackers allegedly trailed participants to the new venue, barricaded the access road and assaulted guests arriving for the programme.
The NUJ correspondents, who arrived in the chapel's branded official vehicle, were among those allegedly targeted.
Witnesses said the attackers repeatedly struck the vehicle and attempted to force its doors open.
When they failed to gain access, some of the suspected thugs allegedly began searching for petrol with the intention of setting the vehicle ablaze while the journalists were still inside.
The journalists escaped only after the driver swiftly manoeuvred the vehicle away from the scene.
At least 20 PDP supporters were reportedly attacked during the violence, while eight persons sustained varying degrees of injuries and were rushed to hospital for treatment.
Journalists at the scene also witnessed another man believed to be a PDP supporter being severely beaten by the suspected attackers.
Speaking after the incident, Nworie accused security agencies of failing to prevent the violence despite prior notification.
According to him, he had formally notified the Commissioner of Police, the Department of State Services (DSS), the Nigeria Security and Civil Defence Corps (NSCDC) and other security agencies ahead of the event to forestall any breakdown of law and order.
He alleged that despite the advance notice, the suspected thugs successfully disrupted the programme and later invaded his residence after the event was relocated.
Nworie further alleged that the attackers vandalised vehicles, chairs, canopies and other valuables at his residence.
The Ebonyi State chapter of the PDP condemned the attack, describing it as an assault on democracy, press freedom and the constitutional rights of citizens.
The state chairman of the party, Chukwuma Igwe, accused agents of the APC-led government of sponsoring the violence.
He called on security agencies to protect opposition members, journalists and other citizens as political activities intensify ahead of the 2027 general elections.
Also reacting, the PDP National Vice Chairman (South-East), Chidiebere Egwu, described the attack as "barbaric."
Egwu insisted that no Nigerian should be attacked for exercising the constitutional right to freely associate with or belong to any political party.
When contacted by SaharaReporters, the lawyer accused of leading the attack, Friday Agbom, denied the allegations.
He dismissed the affected reporters as "political journalists," questioned why they were present at the event and warned them not to contact him again.
His denial came amid calls for security agencies to investigate the incident and ensure those responsible for the alleged attack are brought to justice.
