The demonstration, which started in the late hours of Tuesday morning, saw protestors emerge at the El Wak Sports Stadium to begin the second phase of the march against the worsening economic hardships being experienced by citizens.
The man, who surrendered after he was caught with the weapon, has been sent to the Police station for further interrogations.
Details of who the weapon-wielding individual is are sketchy.
Meanwhile, the leaders of the pressure group have advised all protestors to hand over any unwanted weapons to the Police.
They say they would not shield anyone caught with a weapon.
Speaking to the media, the National Youth Organiser of the National Democratic Congress (NDC), George Opare Addo, noted that the leadership of the Arise Ghana group would avail themselves to any lawful police invite and procedures.
The Ghana Police Service has, however, arrested twenty-nine (29) protesters who allegedly engaged in violence during the Arise Ghana demonstration on Tuesday, June 28.
The arrest was as a result of the involvement of some demonstrators in the “violent attack” on police officers and other members of the public including school children at the Kwame Nkrumah Circle, an official statement said.
The Police are said to be reviewing available video footage of the event and will not hesitate to apprehend all other persons who incited the violence.
Meanwhile, “the organizers of the demonstration will be arrested and put before court for the attacks and damage to public property,” the statement added.
The first day of the Arise Ghana demonstration turned chaotic when protestors clashed with police as they hurled in exchange stones and tear gas at each other injuring some police officers in the process.
