Supporters and police clashed once again before host nation Equatorial Guinea's second Group A match with Burkina Faso at the Africa Cup of Nations.
Some fans allegedly did not have tickets for the game and they reportedly threw stones and bottles at the police, who responded by using smoke grenades.
Hundreds of supporters were involved as they tried to access the stadium in Bata through a single entrance.
It is the second time during the competition where there have been confrontations between supporters and the authorities following similar problems before the opening two matches.
The previous scuffles came after fans were delayed by authorities testing each supporter for ebola before they were granted access to the stadium.
Despite this, the tournament has been largely praised for its organisation after Equatorial Guinea were installed as hosts just six weeks before the competition began after Morocco pulled out of staging it owing to fears over Ebola.
However, both Tunisia coach George Leekens and Congo coach Claude Le Roy have gone on record to complain about the lack of hotels, with Le Roy claiming that five of his team did not have accommodation.
On the pitch, the hosts and Burkina Faso played out an uninspiring goalless draw, while in the evening match Congo earned a shock 1-0 win over Gabon - their first victory at an Africa Cup of Nations since 1974.
Prince Oniangue was the man to write his name in the history books as he stabbed home a 48th minute winner from a corner to leave Congo on the brink of an historic qualification.
Meanwhile Equatorial Guinea have protested to the Confederation of African Football (CAF) after Emilio Nsue had a goal harshly ruled out for offside in their 1-1 draw with Zambia on Saturday (January 17).
Equatorial Guinea Football Federation President Andres Jorge Mbomio has claimed in a latter that there is a campaign to stop the team reaching the next round.
Mbomio felt the decision was a predetermined act by the referee and has invited the CAF to correct the referees and to stop their behaviour.
