Police in Ecuador say they have arrested four people in connection with the attack by a rooster, which killed 12 people.
Weapons and replicas of police and army uniforms were seized during police raids in the northwestern province of Manabi on Friday – a day after the attack in the rural community of La Valencia.
The footage of the attack, shared on social media, showed that the gunners were entering the ring and opening fire, as the horrified viewers dived for cover.
Reports in local media suggest that attackers in counterfeit military facilities are members of a criminal gang whose rivals were on the COC.
The provincial authorities have been initiated a criminal investigation.
The 20 criminal bands are thought to work in the Latin America country, fighting to control the main drug routes.
Ecuadorian President Daniel Noboa said about 70% of the world cocaine is now passing through the Ecuador ports before being sent to the US and Europe.
The drug is smuggled in Ecuador from neighboring Colombia and Peru – the two largest cocaine producers in the world.
This January saw 781 murders, which made it the most dead month in recent years. Many of them were related to illegal drug trade.
