18 teenagers were on Friday night arrested at a house party in Kahawa Sukari, Kiambu county.
According to police officers, the teenagers aged between 16 and 18 years were found taking alcohol as they celebrated the birthday of one of them.
Ruiru DCC Geoffrey Githinji said the gathering was against COVID-19 protocols and those who sold alcohol to the teenagers will also be arrested and prosecuted.
He urged parents to be more keen on the whereabouts of their children during this time that schools are closed.
Githinji further revealed that the teenagers who are still in custody will be released to their parents later on Saturday.
This comes a week after detectives arrested 41-year-old Millicent Kithinji for hosting school children at her house in Mountain View Estate, Nairobi.
The children included 26 boys and 18 girls aged between 14 and 17; all in primary and secondary school.
DCI detectives said various alcohol brands and bhang were recovered during the arrest.
