"Up till now, we deny it," Chief of the Public Information Bureau at the National Police Headquarters Brigadier General M Iqbal noted.
He stated that the police have sought clarification about the riot from officers who sustained injuries in the riot and several terror convicts detained at the detention center.
However, the police have found no strong evidence of ISIS influence in the clash between the terror convicts and police officers, he noted.
"The riot was caused due to the issue of food for inmates. As per the standard operating procedure, the food must be checked by police officers for security, safety, and health reasons," he revealed.
However, he added that the police will investigate the alleged involvement of ISIS in the incident.
"We will investigate it. Up till now, we believe that the incident was caused due to food problem," he pointed out.
Five police officers and one terror convict were killed in the riot.
