Watch as masked men openly walk the streets of Kilwilkie estate in Lurgan on Saturday.
The men, believed to be members of Republican Sinn Fein, walked to a memorial in the estate in what police have described as an “unnotified parade”.
Twelve men have been arrested in connection with the march.
Supt. David Moore said, “The arrests were as a result of the subsequent Policing operation and concurrent investigation.”
