Mr Rotich said two others were killed in Mishomorini and Junda. He said police officers engaged the youth, who were armed with machetes and other crude weapons, in running battles as some swam into the Indian Ocean near Nyali.
“We are hunting the rest,” Mr Rotich said. “We cannot have youth giving residents sleepless nights.
He urge parents to take their responsibility seriously.
Police said the suspects were on their radar.
Among those who fled is a suspected notorious criminal identified as Paul Musau.
“We want Paul to surrender or we deal with him,” Mr Rotich warned the suspect.
In Mwandoni, residents praised the police but called for frequent raids on the dens.
