Guleid Abdihakim, a Canadian national, appeared in court with four other suspects and is being investigated for suspected terror offences.
Kenyan detectives have arrested nine suspects in connection with a Somali militant attack on a Nairobi hotel and office complex that killed 21 people, police said on Friday, indicating the search for possible accomplices in the raid is gathering pace.
A magistrate granted a request from the prosecution to detain the four men and one woman for 30 days while investigations continue.
The suspects are accused of "possible involvement in the nearly 20-hour siege of the DusitD2 hotel and office complex by a suicide bomber and four gunmen who were all killed by security forces, a court document said".

Global Affairs Canada issued a statement on Abdihakim's arrest claiming they are "aware of reports that a Canadian citizen has been arrested in Kenya".
Officials say the attackers were in constant communication with several phone numbers which are located in Somalia.
Images of the bloodied bodies of five attackers were broadcast across social media as Mr Kenyatta announced the end of the siege, which echoed a 2013 al Shabaab assault that killed 67 people in the Westgate shopping centre in the same district.
