Three terror suspects, including a KWS officer, were arrested in Mombasa on Wednesday and 54 AK 47 rifle bullets recovered.
The arresting officer said KWS officer Mohamed Hussein, Roble Kassim and Adan Abdhulahi "are dangerous and might be working closely with al Shabaab's key leaders in Somalia".
The officer, who did not want to be named, said the suspects arrested at Salius hotel on Bondeni Raha Leo street could also be supplying firearms.
He said police sought them after they registered for M-Pesa services in the names Lilian Ayuko and Habiba Mohamed.
Hussein is attached to Tsavo East National Park. It is believed the suspects' rifles are hidden either at the park or within Mombasa.
The officer said the suspects checked into a room at the hotel on Tuesday morning.
Receptionist Mwondu Kiambi said the three frequently visited the hotel since the beginning of the year, alongside other people; police are searching for the hotel owner.
Mombasa Urban police boss Martin Asin said the suspects will be arraigned in court after due process and that investigators will request 10 days to carry out the probe.
They will be grilled at the CID offices and then handed over to detectives from the Anti-Terror Police Unit.
