While taking to social media to announce his presence, Hessy wa Dandora warned that there were young people who wait to waylay other  Kibera residents and night hours and that they better watch out or face the death penalty.

"Mimi natambua jeshi letu hapa Kenya - KDF that comprises of Kenya Air Force, Kenya Navy and Kenya Army, hii jeshi ingine hapa Kibira inajiita Sita Mbili sijui kazi yake ni gani. They operate mostly kwa hako kabarabara ka kuingia Wanga Hospital na ODM office hapo kwa bridge, raping ladies and robbing people seriously while armed with pangas and swords.... As from 2100hrs till morning, just in an illegal operation: Don't say I did not warn you because I can see very soon ntapost maiti ya mmoja wenu hapa!" he warned.

"Wacha waendelee 2,....mostly weekends... Wewe ngoja 2,...they think nimekuja kutafta likes kwa hii group!" he added.

Another undercover cop Blackest Widow was quick to agree with Hessy and add that the criminal gangs had better run away from the neighbourhood.

"Kibera my home...Together we make it safe...Lazima Kurevisit...Kama kuna jeshi nyingine labda la Wokovu...Hawa wa dikwara, ukapi, nyoi na panga-bure kabisa... Wengi naona tu mkiteta nikama mnaingianga round ama mnafaidika na mali ya round iko tu sawa.... Gaza waliwika 'WE BAD' na sai washaukata... Sasa naskia ni #Sita_Mbili... kuna uzito ya aina yake daddy!!! Cheza chini uishi miaka mingi... Wajanja wako Langata! Kama mitaa zingine zimetulia basi pia number nane kitaeleweka!" wrote Blackest Widow.
