Detectives from the DCI special branch unit are hunting for 22 KRA staff who are linked to the tax evasion and bribery cartel that has been bleeding the taxman dry.
One of the officers during the Mombasa raid said that they were looking for those on the run while still building evidence for their case.
There are reports of raids at the homes of KRA staff suspected to have run away by DCI officers in Bamburi, Kiembeni and Nyali estates where computers and mobile phones were seized.
The 22 are part of 100 KRA employees being investigated for various offences.
Staff from other KRA offices in Mombasa, Nyeri and border points are staying away from their offices fearing arrests.
So far 75 suspects have been interdicted and 53 of them arraigned in court already.
In a surprising move, the remaining staff reportedly formed groups to raise bail for their arrested colleagues.
On Tuesday, DCI detectives raided the KRA Mombasa Customs clearance office and confiscated documents believed to be key in their investigations.
Meanwhile, tension and panic continue to grip the remaining staff, with Tuesday's raid being the third in as many days. DCI officers working with intelligence insiders within KRA have been conducting the arrest.
Peoples Daily reported that workers are fearing casual conversations with each other for fear of the insiders planted by DCI.
The KRA board, on Tuesday, in a press release to media houses, moved to affirm that the arrests were part of the tax collector's plan to purge corruption from within.
In the statement, they also affirmed their support for embattled KRA Commissioner General who is accused of targeting his own employees.
KRA board chairman, Francis Muthaura warned against branding the war on corruption as a targeted campaign.
