Nairobi County Environment Chief Officer Geoffrey Mosisria has warned criminal gangs terrorising city residents in the guise of content creation.

Taking to his X account on Wednesday, September 3, 2025, Mosiria confirmed receiving reports from city residents raising alarm over rising insecurity in the Central Business District (CBD).

Mosiria stated that organised gangs are targeting unsuspecting members of the public, especially during weekends, making off with valuables.

According to Nairobi’s Chief Officer for Environment, videos circulating on social media show groups of youths posing as Gen Z content creators but turning to crime later in the day.

“These youths disguise themselves as content creators in the CBD, but by around 5:00 pm, they begin stealing from unsuspecting people. They operate in large groups of 20–30 criminals, surrounding victims and robbing them of all their belongings,” Mosiria said.

He added that some street families have also been linked to illegal activities, including nighttime dumping of waste, robbery, and even using human waste to extort valuables from residents. Such acts, he noted, not only compromise public safety but also fuel unsanitary conditions in the city.

”In addition, some claim that certain street families engage in illegal activities, including dumping waste at night and robbing people before fleeing to the backstreets. Some even use human waste to extort money or valuables from residents. Improper waste disposal and unsanitary practices not only harm the environment but also create unsafe spaces that criminals exploit,” Mosiria said.

“As Chief Officer of Environment, I recognise that a clean, well-managed city is a safer city. Our enforcement team, working closely with the National Police Service, continues operations to remove these individuals from our streets and ensure public spaces remain safe and hygienic. Security and environmental operations are underway, and no resident should live in fear,” he added.

Mosiria has urged Nairobians to remain vigilant and report incidents of illegal dumping, robbery, or suspicious gatherings to the relevant authorities for swift action.

“The safety, security, and cleanliness of our city and its residents remain paramount. Protecting our city requires both vigilance and care for our environment; it is a responsibility we all share,” Mosiria concluded.
