Concerned teachers and politicians have asked parents to stay calm but remain vigilent in the wake of three abduction scares.

Parents have been on red alert this week after a three abduction scares from outside primary schools Surbiton, Tolworth and Worcester Park.

Grand Avenue head teacher Margret Barrington said a letter was being sent out to parents today Thursday, May 24.

She said: “A child did report seeing a stranger in the school and did absolutely the right thing by telling a teacher.

“There was a thorough search of the grounds but because we could not find anyone it was decided the best thing to do would be call the police.”

“They advised us and we acted on that advice.

“Each teacher spoke to their class the day of the incident to remind them about what to do if they see a stranger.

Mrs Barrington said the school was being extra vigilant.

She said: “We are on special look out for anything suspicious until police have downgraded us to amber.

“The children are getting on with school life with minimal disruptions as possible.

“The children are not scared of the police outside as we have neighbourhood officer here quite regular.

“This morning they were talking to them as they were coming in the gates, they are very comfortable with the police.

The first thwarted attempt took place at Grand Avenue Primary School, Surbiton, on Thursday, May 17, where a man and woman allegedly approached a girl getting water from a fountain.

Police believe a man wearing a woolly hat then tried to grab a young boy outside Knollmead Primary School, Tolworth, at about 9.10am on Monday, May 21, but the boy managed to struggle free and escape.

A third incident took place hours later as children streamed out of a Worcester Park primary school at the end of the school day at about 3.10pm.

Police believe there is a link between the first two incidents and have not ruled out a link with the third.

Surbiton and Kingston MP Edward Davey praised the strong reaction from Kingston police and the council.

He said: “This is especially worrying for local parents.

"The response from the police and council has been a very strong one, with community officer visiting the schools “It is very important that these people are found and very quickly arrested.”

Councillor Andrea Craig, education spokesperson for the conservatives, has a child at a primary school in Kingston.

She has advised parents to have a “pre-emptive” talk with their children in case they are approached by a stranger.

She said: “I would tell parents what I have told my children that if someone tries to grab you just shout and scream at the top of your voice.

“We must try and stay calm whilst looking out for anyone who looks suspicious.”

A Kingston primary school teacher, who asked not to be named, said it was important to remain on the lookout for suspicious strangers not to panic the children.

He said: “The kids see policemen outside and they know something is not right and of course we have to stay diligent.

“All the kids have been spoken to here by the head teacher so they are aware of the situation but we must try and keep things as normal as possible for the children so as not to upset them.”
