Another key suspect linked to Mombasa Central police station attack was arrested after police raided a house in Majengo on Monday.
Officers from anti-terrorism police and GSU police units arrested the woman believed to have played part in the September 11 attack.
According to sources, the woman was in contact with one of the female attackers killed during the foiled raid at the police station.
Cyber crimes detectives analysing mobile phone of the female attackers and Rogo’s widow have managed to make progress in unearthing key suspects behind the attack.
Her arrest brings the number of those in custody to five including Haniya Said Saggar – widow of radical Muslim cleric Aboud Rogo, and three women of Somali origin.
Saggar was detained for seven days to enable police complete investigation into her alleged links to terror activities.
Director of Public Prosecution had earlier applied for 14 days to enable his office complete what he termed as complex investigation.
Mombasa Urban police boss Lucas Ogara confirmed that they conducted an operation within Majengo on Monday.
"The operation is going on and officers are pursuing key suspects on the run over the attack at the police station. Details about the arrests will be communicated later," said Ogara.
