Some journalists with Independent National Electoral Commission, INEC, media cards and branded vehicles are being detained in a Bakassi community where they were travelling to cover the election.
One of the journalists, Ubong Umoh of Sparkling FM Calabar, said they and other journalists were detained by armed military men.
He said after a lengthy explanation, the military men still said they should have left as early as 5 am.
He said the military men claimed that they had orders from above to block the road.
There are allegations that foreign elements have reportedly invaded Cross River communities.
A former deputy governor of the state, Efiok Cobham, had told journalists that they got information that mercenaries were allegedly imported by some politicians.
In another development, a party official was reportedly shot dead early morning as voting commenced in Ogoja in northern Cross River State.
The deputy governorship candidate of the All Progressives Congress, Peter Odey, is from Ogoja.
He was reportedly shot by a soldier.
There were claims that the man shot was heard chanting, “APC must win his time…”
The Police Public Relations Officer, PPRO, Irene Ugbo, confirmed the incident.
She said the soldiers were supposed to stay a distance away from the polling units.
An eyewitness account said the deceased, whose name was given as Joe, was a popular commercial motorcycle rider in Calabar.
He had travelled to his hometown for the election.
His death has reportedly caused tension where rowdy scenes are being witnessed, according to sources in Ogoja.
