Schools have been placed on alert after a group of students were photographed walking home.

The group of pupils from The Ramsey Academy, in Halstead, were walking back from school when they believe a woman took a photo of them.

Rob James from The Ramsey Academy said: “A couple of students reported that they saw a woman taking photos of them.

“No student was approached directly.

“We reported it to the police and they looked around.

“They didn’t find anyone matching the description.

“As we always do when an incident like this happens, we sent a message out to parents.

“I would always much rather students report incidents like this and I believe they are much more aware of it happening.”
