The Inspector General of Police Japhet Koome has said the mugging videos circulating on social sites are not from Kenya.
He said they have been picked from other African countries and doctored to appear local.
He spoke during a press briefing on Monday when he met with Nairobi Governor Johnson Sakaja for talks over the increased crime rate in the city.
"Sitaki kusema zinatoka nchi ipi. Zingine ni za mbali. Si za hapa, huo ndio ukweli (I don't want to reveal which country they (mugging videos) happened. Some are from far-off places. They are not from here, that is the truth)," he said.
Koome however said as the country respected the freedom of expression, he was not going to pursue the "editors".
He said he was going to focus the force's resources on pursuing and arresting the local criminals, roaming around the city.
The IG further said the borrowed videos were a way of causing panic.
"Our people are clever I know. They know where the truth is. They can see a matatu painted in blue passing by in the clip. Aren't our matatus painted in yellow? Now you see this is from another place," he added.
Earlier, Koome and Sakaja agreed to form a policing authority to end the insecurity issues in the county.
Koome said that after their lengthy discussions, Sakaja committed to forming the body.
“The Governor will operationalize the Nairobi County Policing Authority as soon as possible,” he said.
The IG also ordered any citizens in possession of illegal firearms to surrender them within a month's time.
He also warned against walking in town carrying guns and knives.
Taking his oath of office on Friday, Koome said crime will not be tolerated under his watch.
He added that the police will use the powers bestowed upon them by the constitution to deal with the prevailing security challenges.
“Any criminal trying to pickpocket or snatch jewellery along the streets shall have themselves to blame as they shall be dealt with firmly,” Koome said.
