Security has been tightened after police raided an Al shabaab terror cell in Malindi Sub County.
The Anti-Terrorism Police Unit (ATPU) stormed the house of the main suspect Samuel Bauzi Obo at Maweni but missed him.
However his wife has been arrested to assist police with investigations on suspected terror activities by her husband.
Obo is reported to be a fisherman operating at Kiunga and resides at Maweni in Malindi where he runs a fish shop at Kwafamau.
The police operation is in line with the resolve by security agencies to disrupt all terrorist cells in Kenya.
Officers from ATPU have indicated that they are in pursuit of other individuals associated with the cell.
Police investigations and arrests have extended to neighbouring counties.
Local security agencies are also liaising with their Somalia counterparts to expand the operations to Raskiamboni where other coordinators of the botched operation are believed to be hiding.
Police are calling on members of the public to be on the lookout and report any individual associated with extremist activities.
