Al Shabaab is receiving funding from businessmen in Mandera County, County Commissioner Fredrick Shisia (pictured) has now warned.
Mr Shisia said the government had received intelligence that the businesses were paying taxes and protection fees to the terror gang domesticated in troubled Somalia.
He accused some members of the community of frustrating the fight against terror and promised swift action.
“Anyone who is in communication with members of Al Shabaab will be arrested and charged,” he warned.
Shisia further stated that security officials were on the lookout for women from Jubaland who are planning to cross into Mandera after being kicked out of their country.
During Mashujaa Day celebrations, appeals for security to be improved in the border town took centre stage with the National government being accused of doing little to prevent terror attacks.
