A social media account which posted "deeply inappropriate deepfake content" which "targeted school staff" is being investigated by police.
A TikTok account which used Grainville School's badge and branding uploaded five videos - with some including staff members.
The Education and Lifelong Learning Minister confirmed the incident had been reported to both TikTok and the States of Jersey Police.
The BBC has approached TikTok and Grainville School for comment.
Deepfakes are videos, picture or audio clips made with artificial intelligence to look real.
